I bought the full version of Power Amp and while it's a great music app I'm having two issues with it. I'm running it on a "AVIN E46 Avant Series Android Stereo Navigation System" in my BMW. The system runs on Gingerbread. 2.34. Here are the issues: Power Amp closes when I launch a Navigation App like Scout. I can't use the steering wheel controls to change songs. (Works on Default Music Player and Radio) The weird thing with the first issue is that if I reopen Power Amp I can hear the NAV system run in the background and I can use Power Amp as long I don't change the screen to the NAV system. If I keep Power Amp or any other window as the focus other than the NAV app, Power Amp will keep playing. Fustrating since I would like to use Power Amp instead of the default music player as the sound quality is so much better with Power Amp. Thanks!
