Boss player double din

This player is of a good quality, got it recently so far the player's features are just as it was outlined, met my expectations. The only thing is the display for the radio, its a bit old school but thats not a big issue if your not too picky. USB Capability is excellent, major reason I bought this deck. If you looking for a relatively priced unit, this is the way to go with your features that will meet your expectations.

Installed in a 2000 Jeep Cherokee to replace the factory radio.  I installed a new Pioneer single din head unit and it fit great with this surround.  The little pocket takes up the extra space left from the original 1 1/2 din factory radio.  There were two X-shaped pieces of plastic I had to trim off where the head unit sits, but otherwise not other modification.

The Boss audio BV79488 receiver was easy to install, sounds good in my 2001 grand prix and the price was good too.

The most great wonderful double din stereo I have used. I have installed it in 2008 Mercury Grand Marquis. A little bit expensive, but it worth it.

I must say I didn't expect this product to work as well as it do. I figure out  how to get the best sound out of the Boss. In order to get that quality sound go into your radio settings and set up your sounds through PRO EQ. My system sounds great.

Excellent Head Unit. Has everything you could ask for and more. Harness installation was easy, and the setup afterwards wasn't difficult at all. Menus can be a bit of a headache at times. If anything, the radio might have too many features.

I bought and installed this in my car. I absolutely love the Sony Head Unit. It has this ZAP technology that plays clips of songs off your MP3 player like the scan feature on the radio but it takes music from the middle of the song.
  Only thing is the the Sony speakers it comes with are pretty poor quality. They are basically tweeters. They can not handle any low frequencies and distort because of them. I installed them in the back so I don't have to listen to them while driving.
  The head unit is worth the price though. I love it's features and it even looks really cool lit up at night!

The FDZN4 module was a simple install. If you are not afraid of taking your dash apart you can have this installed in about an hour. The only drag is finding a switched hot wire. Your best bet is near the base of the steering wheel.(use a dc lead finder) Sound is what ever your stock radio provides with no static or interferance that the FM mods have. All steering wheel controls still work including seek to advance songs on your zune. If you want to listen to your zune in your ford this is the way to go.

Installation:
I installed this on my 98 Silverado which had a 1.5 DIN original radio. Bought a Scosche GM1483B GM02B MDA1B Dashboard Installation Package which came with a wire harness adapter, antennae extension and 1 DIN to 1.5 DIN bracket, etc. Wired up the wire harness adapter color for color with the supplied radio harness in this kit using 16 wire gauge butt connectors. I was only left with two wires that didn't have matching colors (Orange & Blue) which were not items I had anyhow. Every wire was labeled neatly. I used the longer of the two supplied mounting metal brackets to push the unit a little longer out the opening to clear my AC switches. The only issue I had was the longer finishing bezel didn't fit without cutting back some of the dashboard installation kit, so I used the smaller one and it still looks good and everything is locked down. Installation took about an hour.

DVD:
To get the unit to play DVD's, you can either ground the brown wire to the parking brake switch as advertised or you can just ground it with the black wire to the automotive ground or even the metal bracket that goes around the unit will work too. This way you can play it when ever you want.

Operation:
The unit is plenty bright enough and can be adjusted. The radio works great and was clear and plenty loud enough. The BlueTooth (BT) works well. I paired it with my iPhone 5 with no issues and was calling over the radio quickly. The volume and connection was loud and clear. Haven't tried the USB or SD Card interface yet but I'm sure those will be fine too.

Comes with a screen pouch for when you want to remove your screen and the remote works well too.

I own a 2012 Silverado WT with the most basic AM-FM stereo factory radio. Since there's no CD player or AUX input, all I wanted was the ability to listen to Pandora on long trips. Now in the old days, you'd go get a good aftermarket head unit/ all in one radio, a mount kit and a wiring harness adapter and swap.  The problem today, is that your 'radio' is a lot more than just an entertainment device- it's part of the vehicle's overall computer system and the display is used for operating diagnostics. To go aftermarket now includes a data adapter and usually headaches,
This brings us to the BOSS FM20- A metal box slightly smaller than a box of cigarettes with only a few wires. There's a +12VDC wire that goes to your switched "ACC" power, a -12VDC ground, a short antenna wire and 2 RCA female connectors for low power audio input.  Find a vacant FM frequency, program it into your radio, set the 4 DIP switches on the box (note switch positions!) do your electrical work and you're good to go.  Using a Samsung Rugby III as my source, I had no problems pumping tunes through my radio.
Overall I give it 4*, as you do get some hiss coming through at high volumes. My only gripe was the execution of the cables. The wires are soldered to the p.c. board and held in place with a dab of hot glue- a point of failure, especially in a vehicle.  A few Ty-Raps inside the box did the trick, but for pennies they could have put in some proper strain relief.
Considering the modest price and ease of installation, it's a good fix for the non-audiphile

Paired with a set of Boss ch5720 speakers gave my Lil Dodge Dakota some good sound.
Even though radio says it has a remote wireless. Mine was not in the box. Not was it in the replacement radio they sent. So don't get your hopes up for the remote. None the less, I'm truly satisfied with the radio itself.

I love my Pioneer Double Din because of it's bluetooth capability. My cell phone automatically connects every time I enter my car and the music output is pretty good.

I purchased 2 of these players and installed it in a Lexus RX350.  I liked the fact that I could install power permanently in the vehicle thereby minimizing wire clutter.  I ran the wires through the seats and out the bottom and connected the power wire to an accessory power source in the middle console (cigarette plug) to ensure that DVD player is off when car is turned off to avoid battery drain.  I connected the RCA plugs together from each unit to allow each DVD to be able to play its own DVD while also being able to watch the other DVD player/  Due to my inexperience, locating the right power source and the fact that I removed both front seats to install power to the center console, it took me over 4 hours.

Picture quality:  The picture quality is really good when playing DVD's.  However I did notice some video quality degradation when watching the video being played from the other unit. This is caused by the analog RCA plugs and is expected.  The screen is big and I like it.

Sound:  The speaker sound is decent, but not loud.  Using the wireless headphones is better and the sound quality is really good.  I have not tried the sound through the radio as it wasn't important to me.

DVD Player mount:  The DVD player mount was easy installation and one screw removed allows the entire unit to be removed leaving the mount in the headrest.  One thing I noticed is that the DVD Player has vibration when I drive and the unit bounces up and down.

Remote Control:  The remote takes some time to figure out and I did have a problem that when I used it on one, it also controlled the other unit making it challenging to use at times.  I wonder what the impact will be when both kids are trying to play the games at the same time.  I like the fact that this unit also has controls on the face of the DVD player making it easier to control.

DVD Player:  I liked that loading a DVD was from the top and that you didn't have to go to the back of the unit.  Easy loading.

Games:  Surprisingly, the games that come with the DVD player provide a lot of entertainment for the kids,  They like the games.  They had not played the games at the same time so I do not know if there are any problems with the remote control controlling the other unit.

Headphones:  One of the reasons I selected this unit was for the folding headphones (the other reason was for the top loading dvd disc).  I would have prefered the other headphones as these seem to be less quality.  But they work very well.  (BTW, one headphone didn't work when I received it, but the seller immediately sent me another.  Excellent Customer Service.)

In all, I am very pleased with the DVD player.

I was looking for a cheap way to replace my stock CD player with a head unit with BT and AUX inputs. I came across this product and decided to give it a try. It was easy to install using a Metra wiring harness. Works great. Only problem is BT sometimes takes a few minutes to connect, but this is not enough to deduct a full star.

don't expect it will give u the BIG BOOM and cover the whole parking lot (u shouldn't be looking at 10" sub at all if that's ur goal). however, it give nice and sharp bass, which gives the music a really nice touch up or cover up the weakness of factory stereo. most importantly, it's relatives small and no need to sacrifice much of trunk space!!

Device was installed in a 2007 G35 Manual Coupe using this video: https://www.youtube.com/watch?v=sHRITRi_gII

The installation is pretty straight forward however, I do have some car stereo installation experience.  The sound quality is leaps and bounds better than my previously installed FM modulator.  The unit was small enough to fit directly behind the factory stereo and the 3.5mm plug and wire was long enough to make to the arm rest with some slack remaining.  The only reason I did not rate this 5 stars is because the plugs that go into the iSimple adapter box  can fall out easily because they don't snap into place.  That being said, be mindful when putting your stereo back in that you do not inadvertently knock a wire out of the iSimple adapter control module.  I recommend testing your connection before you put all the radio screws back in to make sure both channels work.  All in all, very inexpensive way to upgrade your factor stereo to receive two aux inputs.
