Good unit.  Worked as advertised.  My Sprint Samsung Epic smart phone was charged fully and the unit turned off by itself.  Recommend a buy for others :-)

I am pleased with the box not so much the interface though but there are a few Unofficial firmwares which fix this, other than that the unit works great.

The Unit:
Clean looking unit the LCD could have been put to better use but it is ok, Red standby button needs to be amber color so it doesn't look so bright.

Remote:
A few buttons are unused but you get used to it after a few days.

Playback:
Plays any video I throw at it AVI MP4 Divx etc etc from internal, USB, or NAS shares. No problems with stutter or freezing like some stated here, may be a badly encoded file as well.

Gigabit:
The transfer speeds are a bit slow but that is a Realtek problem not a Pivos that use this chipset, just pointing the blame in the right direction.

Web Browser:
Yes is it limited with the lack of Flash support, so is any Iphone, Ipad, Ipod Touch. Get over it HTML 5 is coming and here to stay.

App:
Specifically Youtube works fine, for those that cant get video to play update the firmware. Google likes to change the API which breaks these apps.

It works! many of the complaints about the unit are usually fall on the end user either lack of following directions or improper setup.

The VPD4000 is a nice unit that had buttons to navigate the menus and functions. One complaint by others was the buttons on top were a bit hard to use since they were on the top of the unit and you had to keep turning the unit on its side to see the buttons until you got used to them. Creating a black jpg 800 x 480 with text at the top of it to show what the keys do ((||Stop  < >  Up Dn  Enter/mode )and then set this as the wallpaper for the unit. This really helps using the buttons without having to turn it on its side for menu mavigation. Another neat thing you can do is put your name and address phone number on the bottom in case you loose it and some honest person finds it. BTW you have to put the Enter/mode on the 2nd line from the top so the battery indication shows. At first I thought the buttons were a disadvantage but now after reading some reviews of touch screens I'm not sure they are. They are positive and you don't have to worry about miss hitting  or using a stylus  or starting something you didn't want when you have it in your pocket.

The VPD 4000 is actually a china ainol v6000 rebranded for US with english manual (on line) and startup procedure (No FM radio on VPD4000).  Music seems fine with a library function (local disk only ) supporting ID3 tags and ability to find music in sub directories of the local disk, and 2 minisd. Videos play fine. Screen is hard to see in a car in the middle of the day, its ok at home. Battery life seems ok and the battery screen is good. Video out to a HD TV is thru a set of component cables and to use on analog tv you need to use both cables provided (green one for video). HDMI would sure be nice. The remote works ok but the range is very short and using it helps navigate the screen easily. A nuvi case fits the unit nicely. I've put a 8GB mini SD in the unit and it works, I haven't tried 1GB. To use a USB Flash you will need a USB to mini usb adapter. Unit has a 3.5mm headphone jack, and comes with a AC wall charger that takes several hrs to charge the phone. Earphones that come with it are at best marginal. All in all its a nice media player and very good for the price.

This unit has worked very well. Once in awhile it's gotten out of sync with my phone (phone says it's connected but it's not working) but that's only happened a couple of times. An inexpensive way to Google Play Music from my phone to my home theater system.

if u get this thing,the first thing to do is get some whiteout and paint the annoying led lights.ok so unit tested on.cs4k(android tv player) using firmware from company dated dec 18 2014.almost everything works in xbmc and android screen.

1.i had this connected to a usb wire hub.keyboard would make xbmc do wonkey things onscreen.i plugged directly into the unit and wonkyness was gone.

2.wireless range is good.i'm sitting about 13 feet away from the dongle and it works well so far.

3.touchpad works like it needs too.no problems there.mouse left and right buttons work well.theres two on side of keyboard and between the touchpad.

4.home button does nothing.the E(browser button) is home.rewind and forward does nothing.vol up/down work.play/pause button works.

conclusion - it's a pretty neat keyboard.very lightweight.snappier to use than the regular remote that came with my unit.i need to figure out how to configure a menu button.plus configure some buttons around to make it more my taste.hopefully i can fix the rewind and forward button.wish it had a on/off button.

We bought a manufacturer refurbished unit.  It works great.  The only minor disappointment is the 5G band signal strength is significantly less then the 2.4G strength, but apparently this is common.

I installed one of these in a 2008 CTT w/Bose and it went well. It came with the MOST interface for $730. Is also came with 3 other different ~10 foot wiring looms for other radio options i presume. Basic install to get quality sound, steering wheel controls and dash info was plug-n-play. I needed a ground-loop isolator to completely remove a minor alternator noise. Getting the Porsche backup camera took a little work, but looks great on the larger screen.

Overall Review: Love the install; came preloaded with Porsche boot logo and all the steering wheel controls mapped. UI is fast! Having Waze and Google maps and streaming audio apps is great! You have full control layout the 3 homescreens, but I cant figure out how to change the buttons in the launcher bar at the bottom. Bluetooth phone works great. Bluetooth music streaming has some glitches, but that might be my phone. The device is limited to 2G of memory and this limits how many apps can be installed. There is external memory, but few apps support moving to external storage. The UI Boot up time is about 15sec, but the FM (if that was the last source) and backup camera (when reverse is selected) start working almost immediately after the car is started.

FM reception review: The Seicane only has one Fakra FM antenna input. Using one of the two FM antennas gave mediocre reception. I had to get a couple connectors to merge/amplify the Porsche diversity FM antenna and then convert back to Fakra connector. The FM source is slightly louder than the other media sources and requires a couple click of volume adjustment when switching back and forth. Once I get 4G data working, Ill probably never use FM again.

Mobile Data: The 3G usb dongle they sell is for T-mobile only and reception was poor. the radio does not work with the one 4G tmobile dongle I tried. Im using my phone hotspot and android screen cast, but Ill probably endup getting a mifi for the car.

Basically a tablet with a single din stereo grafted on. There is definitely some custom android OS work in here and I don't expect and upgrades or after market roms. All-in-all a HUGE upgrade from OEM and im super happy with it and the price.

I got a NewTrent Easypak NT70T to review from the company and it did a great job of charging my Samsung Galaxy S2 while on a business trip.  I also have a PowerGen PGMPP6000 mAh External Battery Pack which is comparable.

The NewTrent Easypak NT70T is rated at 7000 mAh, has a micro USB cable in the unit, a USB cable built in the unit for charging, and a 2amp and 1amp output to charge various devices such as smart phones and iPads.

The unit itself only came with a USB extension cord to charge your device, so you would have to use your own USB charging cables to charge various devices ... unless you have a device that uses a micro USB cable of course.

The unit itself is a little larger than the PowerGen PGMPP6000.  Even though it was a little larger, I did find that the micro USB cable built inside the unit was sturdier and it didn't feel like it was going to break.  It also felt more comfortable having the two units together while charging.

Charging

This unit was able to charge my Samsung Galaxy S2 2+ times using the 1 amp output.  I only charged it when it was below 20%.  It's not an exact gauge, but it has enough juice to keep your phone charged when needed.

I also tried charging an iPad 3 using the 2 amp output.  I didn't get a chance to measure how much of a charge it could produce, since I'm usually at home while using the iPad.  If I happen to go out, I make sure that I charge my iPad fully which is usually enough time for me to do what I need to do on it.

One thing that I noticed is that you don't have to power on the NewTrent unit to start the charging process; it will just start charging the device when plugged in.  Also when the NewTrent device is completely dead, it took about 8 hours to recharge using my Samsung Galaxy S2 charger.

Overall thoughts

I thought that this NewTrent unit provides great value for the price and comparable to other external battery packs out there right now.

So what makes this unit stand out from the others?  One thing that makes this unit stand out is that it has 2 different outputs for various devices that you might need to charge different devices.  The only downside is that you have to provide your own USB charging cables.  It's not that bad since you will have the cables anyway.  The micro USB cable also seems a bit sturdier and doesn't seem that it would break easily as the PowerGen unit.

If I had a choice on the PowerGen or the NewTrent, I would get the NewTrent.

9/9/13 Update: I used this to charge an iPad3 and the NewTrent Unit was able to charge it from 0% to 30% on a full charge.  This is more than enough for my needs when I'm out and about and need an emergency battery back up.

Great card. I got this for my Samsung Galaxy S 4G phone. So far it's working great.
Don't be afraid to buy it. It's a good card at a very good price.

Just bought it, but no issues so far.

It would not work on the same line with my ATT satellite box, but works fine on the line with my bluray player.

Does not seem to include a power cable for the port on the unit, but it works without it.  (for me)

This works perfectly with my device. I have an old iHome under-the-cabinet radio and when I switched to an Android phone I wanted to find a way to keep using it. My Samsung Galaxy 4 pairs easily with CoolStream Duo and I can play Spotify, Pandora, or my personal music through the iHome speakers.

The only drawback I can find is that the iHome speakers must be turned up to a much higher volume than typical, even with the phone's volume turned all the way up. I have to remember to turn the volume down in case my husband turns the speakers on to listen to the regular AM/FM radio.

I bought this to replace a 5 year old unit. I didn't replace the antenna, just the booster. Without a booster, I'm lucky if I can make/receive a phone call form the bathroom.  With it, I can make/receive a call from anywhere.  With my old unit, I was able to receive 3G on my MIFI.  With this unit, I'm getting 4G!

Update:  I lowered my review from 5 starts to 2.  I only got 2 years out of it before it died.  When I first installed it, I saw a big difference:  added 1-2 bars.  Lately, I was wondering if it was working and last night it died.  Way too expensive for what I got out of it.  Off to find another.

Pretty good product.  Only problem I have is it is not 4G. If you fix that it would get 4 stars.

Works amazingly well for what it is. I bought this for my shop after originally installing a larger similar booster for my home from my service provider.  In our rural location cell service is iffy at best.  This unit was installed using the supplied antennae on an outdoor mount.  I just used 1" EMT electrical conduit as a mast at 15' above the ground.  I built a brace to hold it against a small outbuilding attached to my main shop.  I just guessed on the antennae's orientation based on my home boosters direction.  Since this is a directional antennae and not omni-directional, knowing where the cell tower is, is a must. I wasn't sure how much cable was supplied and it turns out you get 2 rolls of about 25'-30' each. I bought an additional 50' roll, but it turned out I didn't need it.  If I did need it, it would take adapters to connect to the supplied cable.

The units install easily by attaching the cables where indicated.  After turning my cell phone "OFF" I just plugged the cell booster in to power and WHAM, I immediately upon turning my cell phone back on I had 3-4 bars and 4G in an area with NO bars and NO "G".  It actually gets better reception than my big expensive service provided one does at the house.
The negatives are that it has limited range, probably due to this being the runt of the litter of WEBOOST.  I can walk out a door 10' from the antennae and drop a call. As long as I stay inside my shop I can talk on the phone. Going out a door is a call dropper.
I will fine tune the direction of this antennae and see if it helps even more.
Another issue is that the indoor antennae only has a short cord (about 6'), limiting it's placement from the main inside boost box.  It also uses a different size cable from the outdoor antennae.
The written installation manual was rather lame. It refers to you going online for better instructions. Not a good thing if you're a long way from internet service while installing.
For what this costs, it certainly was an inexpensive option compared to what some of these things cost and worth it.

This was used in combination with 2 other amazon purchased items to provide a cell phone connected signal to stream XBMC and Netflix to a second TV too far in the house from our router to receive reliable WIFI signal:
MHL2 media cable  http://www.amazon.com/gp/product/B00ESM3TTA/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
DVI to HDMI adapter  http://www.amazon.com/gp/product/B009W8FVCI/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
and an HDMI female to female extender adapter  http://www.amazon.com/gp/product/B00D8GFBK2/ref=cfb_at_prodpg
I attached to an old but serviceable LG TV's DVI port (no HDMI port) the DVI to HDMI adapter.  From the HDMI end of that adapter, I attached first the "Female to Female" adapter, and then to that, with the MHL media cable was able to connect to a Samsung Note 3.  From where I could stream all that was visible on the phone's screen to the TV.  As long as I follow the MHL cable's included instructions EXACTLY, each time I hook it up, this setup works a charm.  Takes all of 5 minutes.  The only aspect of this I am uncomfortable with is that the phone has to be turned off when connecting, then back on to be recognised at the proper instance.  I don't like booting devices more than necessary.
Hope the due diligence I did on each of these 3 cabling devices pays off for you.  Just make sure you get the right MHL cable for your model of phone, and I'm sure it will work.

This item works nicely for the Sprint GalaxyII Epic Touch.  The connections are firm and positive, I have not had any problems.  My Sony LCD TV mirrors my phone immediately when I plug this in.
