I'm having the charging issues as well (charges with wall outlet, not in car) but I've also noticed something else. If I try to use a streaming music app (Sirius/Slacker/Pandora) it works for about 5 minutes and then goes silent. Once one app stops playing none will work until I reboot the phone, and then one will work again for about 5 minutes and then stop. Doesn't matter which app I try to use. They all do the same thing. I've un/reinstalled all of them with no improvement. Has anyone else noticed this?
