Final update on this. I ran into an issue where the connection between the dock and tablet seemed to be hit or miss. Thinking it was the dock I tested it with my spare new one and had the same issue. I tested my sons tablet and it worked fine. Just when I started to remold my dash for an integrated install I really started to weigh the pros and con's of my install. The number 1 con has always been the lack of hands free calling. Tablet-talk has never been a viable solution and the IP calling options were spotty at times so they were not viable for me. The 2nd con was engine noise. I installed line filters but could always hear a small hum/wine through the speakers. Ultimately I think it was the amp. With these 2 cons I decided to try the pioneer appradio3. Once installed I decided to use mirrorlink and found with automateit and the same apps I used on the nexus7 I was back to where I was with the tablet except I had hands free now. The only con with mirrorlink is that it is built on vnc so there is a little latency which means videos are a no go. Shouldn't be an issue though since this is for vehicle use.
When I was thinking about a nexus 7, that docking thing sounded like the perfect solution. now that I've went with the galaxy tab, I'm having trouble figuring out how to make it removable, but still give it power.
I hate to see you abandon it. I've been through the same sentiment though, but all in all, android is simply way better than any software the current headunit makers have. I don't see what's keeping Sony, Pioneer, etc... from simply making an Android based head unit. For fear of using it while driving they can still include the parking brake function to enable certain apps, but of course we could still bypass it.
Sorry to bring this back from the dead but I thought I would touch on your comment:
I have no idea why HU manufactures are not utilizing a true Android interface. It probably has to do with it being open source. I've been using my S3 with the Appradio 3 for almost a year now and the only main issue I have had is with the mirrorlink app. Samsung hasn't updated the app (DriveLink) in some time and the modified version allowing mirroring is all but abandoned as well. Due to this I have switched to App Radio Unchained which uses HDMI for video / sound and bluetooth for a keyboard to allow the touchscreen to work. Both solutions I tried required modified vendor software to give the experience I wanted (mirroring my phone and doing the same functions as the N7). Pioneer has limited native support for apps out of their appradio line and without the mods the appradio line is very lacking. I can see why they have dropped it for the more expensive NEX line as it combines their fully functional nav unit with the features of the AppRadio.
Now since most of us here are the hack it and use it crowd, the appradio seemed like a great option given I knew it would require some work to get it to function as well as my N7 did in the truck. The main perks was the ability to use hands free calling, and a simple backup camera option. The major downside though is that I can't point to the AR3 and say look what I did.
