Must have General Mobile Radio System license.

Radios work well. Product description should tell you this radio uses full power on channels 1-7 and requires a GMRS licence as opposed to Family Radio Systems that use the same channels on low power.

Works fine, but needs to be part of a system including a receiver that is capable of driving it.

Manual contains all the information needed and comes with a disk that takes you through all the possible multiple choice question that could be on the FCC exam for a ham operator General license. Manual itself is arranged logically, and builds on the study guide for the Technician exam. There seem to be some minor math errors in it, so you need to be a little careful about doing the math. Some explanations of the answers are a little vague, so you just need to memorize those answers for the test. There are about 400 questions total on the disk and in the book (same questions). I haven't taken the exam yet, so my final evaluation is pending the results.

It was expensive, but I liked the small handheld format. This isn't something I'll use often, so I didn't want a permanently mounted radio. Worked well with an external antenna.

Vendor prescribed wrong device for my car . Recommend first check with dealers to verify correct device FCC programming type before purchase.

Mandatory equipment for a mobile tech.  Nice quality cables and connectors.

I've had dozens of different FRS / GMRS radios over the years,  and I picked these bubble pack units up specifically because they are repeater capable.  Any commercial grade radio that supports transmit / receive offsets is in the couple hundred dollar range, so I wanted to give these a shake.  You really can't touch the amount of features when you consider the price.  Being able to have the weather alert activated while still using the unit for communications is a plus, and I know it's only a 50 cent feature, but the flashlight it a nice little addition too.  If you are expecting 10, 15, 35, who knows how many miles they all advertise, then you will be disappointed unless you are both on nearby mountaintops.  This is line of sight communication folks.  If you want a radio that's full of features and is reliable to boot, then I'd recommend.  KEEP IN MIND - You need a GMRS license to transmit on some of the channels this radio supports.

This is a great radio for a ham -- it's 10 meters and is built well.

But, this is not a CB, a hybrid CB or anything to do with a CB. This is a ham radio. 10-meters requires an FCC license to operate.

If you don't have an FCC Amateur Radio Operator license and you use this radio you can be fined. The FCC fine usually costs $25k for unauthorized usage.

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.

Nice little radios for the price. The package says you need a GMRS license to use all 22 channels. I could not find the actual power output listed anywhere, but the performance is compatible with other 0.5 watt radios.  No PL tones.

This radio has it all. And I would recommend a professional install. It has to many options to allow for a DIY job. Great buy for both Apple and Android users.

When I received this item, it became apparent that it required a separate base station to operate the phone.  That would have to be another purchase that I did not anticipate.  No where in the advertisement did it state that this was an extension of another item.

I was able to return the item but the cost of shipping both from and to the seller was expensive.

Chose the product based on recommendations of other ham operators.  Price was right, but the instructions need to be better.  Gr

So far they are working great but wish they were part 95 compliant so I can use them without a ham license. I ended up buying part 95 compliant radios for use on the GMRS and MURS freqs and will use these as emergency radios until I get my technician license.

Great features in a moderately price VHF radio. The GPS is able to pick up a signal inside the cabin. Good sound quality.

We were looking for radios for our church safety ministry just to get us started.  I am a rule follower and wanted to track down the details on licensing and if we needed to obtain one for our use.

I contacted the FCC directly and was informed that because this specific radio is CAPABLE of transmitting at 5 watts it REQUIRES the user to obtain a license.  Even if you are using lower power or only operating on former specific FRS bands.

Because GMRS is only used for individuals each safety team member would have to have a license unless they are "immediate family."

The radios have several good features and would be excellent for family use hunting, camping and the like.

But be aware that the fines can be steep if caught transmitting without a license and from I understand has criminal penalties to include jail.

Hope this helps someone as I spent many hours trying to figure this out so we could do the right thing.
