Been using the sandboxed android auto and I seem to have intermittent success with it it will always connect but sometimes after a few songs (using simpmusic) it says source error and then I basically have to power cycle my car. It is going through a wireless dongle but prior to graphene I was using the same setup with simpmusic and had no problems. It does always tell me I need to update Android Auto so I don't know if that's an issue. But I've even tried to just install AA from the play store but then it says it can't install for some error. Any ideas?
