1. There's no AOKP-wide GPS issue. It's working great for a lot of us. Please re-flash (clean), and try it again. Also, if you're restoring Maps from backup, don't restore data. That will frequently cause issues (not necessarily GPS issues, but issues are bad regardless). Also, make sure you're outside, or very close to a window. I know that on my device at least, if I'm not outside, there's only a small chance of getting sufficient satellite locks for it to pinpoint my location. Also, my device is crap when I'm in a heavily wooded area like my local parks. I don't know if it's the same for everyone, but I'm assuming so (I could be wrong though, who knows).
2. Wakelocks from Maps happen frequently. A couple things to try, go into Maps, then Settings, then Location Settings. Disable everything in there. All of those settings are for Latitude, and should have zero effect on Maps or Navigation. Also, go outside, start up Maps, and wait for it to say Location Set By GPS. Then back out of Maps. You shouldn't see excessive wakelocks afterwards.
3. Bluetooth connection (not necessarily playback quality) issues...yes, it's real, stop posting about it please. Zaph is aware of it, and I'm assuming other dev's are as well. Until someone posts something saying it's fixed in whatever change and that it should be included in the next release, please assume they're working on it. If it's absolutely critical to you, please go back to a 4.2.1 or 4.1.x release until it's fixed, nobody will be offended.
4. If you didn't clean flash, and you're having issues...too bad. Sorry, but it's always recommended to do a clean flash. If you can't, and you do a dirty flash and start having random issues, you brought it upon yourself. If you dirty flash and everything works great, good for you. However, please don't tell people "hey, it works just fine" unless if you want them to contact you directly for any issues they have resulting from the dirty flash. We all have different setups, and any one little piece of old data can cause bootloops or FC's. The thread really doesn't need to be clogged up with people asking for help with issues they brought upon themselves by not following the directions.
Sorry...after a dozen pages of people talking about the same issues over and over, it just gets a bit annoying. Maybe I need a vacation...
