[Android Head-Units] TeamADW:
Mirrored from my Amazon review on this unit:

Here are all of the pieces we purchased with the A62721PB 2G/32G, in order to install in our 2006 Dodge Ram 1500 truck. Install is still not complete, but I'll get to that in a bit.

As you can see, its an ordeal to install this unit. Even the manufacturer doesn't seem to understand the vehicles it will be installed in, in our case, a 06 Ram 1500. Standard Chrysler wiring (would be the same for almost any 06 Dodge, Chrysler, Jeep... etc) telling me to tap into the -5v canbus wiring as the accessory switch. To properly install this in those vehicles, you need a CanBus adapter, which will give you the ability to turn to ACC and run the unit, and allow it to dim with the interior lighting. Neither of those are done in a 12v switched wire in these vehicles. Oh, and you will need an antenna adapter too... both of these I have yet to buy . If you have more than basic radio functions in your vehicle, you need a better install kit. Basic wiring wont cut it to do the job right.

As it is, I used a tap to the ignition switch (+12v) to turn the unit on until I have a few bucks to pick up a proper install. So think of all of that when buying. To get all the functions, you need more parts, so a $300 radio turns into a $500 radio quick.

OK.. Use. Most of my use is with Google Maps, Amazon Music (offline) or the backup cam. Getting those or any software setup with large downloads was a pain, as this unit shuts off the wifi with the key, so no updates while you sleep, and no way to turn that functionality on. Unless you leave your keys in the vehicle (not the best choice). And with the sub-par performance of the wifi in this unit, its going to take a while. I can see my home wifi all over my property with our phones. The truck only seems to see my neighbor's connection. The antenna is mounted under the black part of the windshield trim, just out of view. In fact, the only good reception I've gotten is with a portable hotspot in the truck. The A6 also cannot seem to see our 5gHz channels. These seem to be built to the same standards as generic 2010 tablets.

The built in pairing is useless. It just shares the screen image with the head unit. No controls, no passthrough... just video. If I wanted to use my phone I would have stuck to the ram mount. PDA-Net is the only way I've been able to connect, as my phone plan doesn't include wifi hotspot.

Speaking of phone hookup and this unity, you can share data (like PDA. net) or use fast charge. not both? And those USB leads really should come with some sort of bracket and template for in-dash installation. We plan on making these, but really, it would be a lot nicer to have it come with. Right now, they just fall out of the bottom of the dash like an afterthought.

Additionally, we negated to install the microphone. Most times people can hear you fine. If not, you have to re-boot the system. You also have to reboot when it wont pause music when a call comes in, or lower sound when the rear camera activates.

-Side note about that pause... most sub $30 bluetooth adapters resume your media when you start the vehicle back up. not this one.. you got to hush the FM software, navigate back to your music (Amazon music in our case) and then hit play. Since there is no play button on the factory remote, its a real pain in the backside. Not well thought out Atoto. -

Reverse cam is basic, we bought the matching ATOTO one and the quality is garbage. Looking for a better unit now. Nice that it just lowers the music while backing up, and doesn't cut out though.

I haven't tried to install a better home screen or layout in this unit. It would help to have a bit more open framework. The colors and designs are bland and garish at the same time (congrats on that hot mess Atoto) with no support for changing them.

The best looking interface and use so far has been Torque, which we have the pro version of, and has been useful to see a few tuning parameters as well as info for towing. We bought a generic ODB2 dongle and it works fine. The downside is the built in browser for looking up a trouble code that came from blowing out our dash lighting during install (dumb grounding mistake, should have known better and pulled the battery leads. ) No support for acceleration sensors though, seems the A6 does not have them. So if you want this for your autocross car, maybe skip it and just use a used Samsung Tab or something.

Im going to look into re-flashing the headunit after we button up the install with a better ROM, better apps, and hope I can find a good dashcam utility that works for this. CarWebGuru works at first, but then on re-boot will disable all sound, cameras, and the remote if left as the launcher. If not, it still works, but is kindof redundant.

overall, its a project. Take a full day to get it all installed, maybe longer to dial it in right.

Overall, so far, we spent a total of $368.17, and will be spending at least another $80 on this unit. I guess that is the name of the game when you want to do things right, and not spend $800+ on a turnkey system.
