[Q] Newbie pre-purchase N7 2nd gen questions, intended use = car stereo head unit
Hi all- pointed here from a friendly person over at another website forum.
I got interested in the idea of using an N7 as a head unit (car stereo replacement) shortly before the 2nd gen devices were released. I decided to wait, but when they were released I was reading lots of bug reports, and decided to hold off. Now that it has been a few months, I'm looking at it again and am hoping someone here can point me in the right direction or answer any of these questions. I did a general search, and also searched this website before posting, but I haven't found anything definitive.
The intent of the unit would be to provide googlemaps and mp3 audio. N7 would be slaved to my phone, so the wifi model is fine. My current car radio does not have an audio input, so this would be a complete replacement including a small amp
1. Are the N7 2nd gen original bugs (GPS and ghost touch) completely fixed now?
2. Is anyone aware of any how-to or walkthroughs specifically using the 2nd gen N7 device as a head unit (replacement car stereo)? I found a couple of posts from right after the release saying that they couldn't find an working image (root? kernel?) to allow simultaneous USB charging and USB audio out. I haven't been able to find any posts where people have figured out (and explain) a way around this.
3. From what I understood from the G1 postings, the root was needed to enable the USB audio out, but I read a non-headunit post that claimed this capability would be embedded in Kitkat... but haven't been able to find any confirmation
It is quite possible that I'm just not searching the right terms, so I welcome better search terms to use (vs "Nexus 7 2nd gen head unit") or actual links to pages that either show how to convert a N7 2nd Gen to a head unit, or that are current and describe the remaining problems so I can follow those threads,
