When I use bluetooth to stream music instead of plugging in, I get little maybe half-second dropouts, almost like little skips. It happens consistently, any song I'm listening to. I've always assumed it was just a bluetooth issue, but my friend just installed a Pioneer unit in his Mustang and doesn't seem to have those problems. Now, granted he is using a different phone and a different head unit (both of which probably have newer bluetooth protocols), but my question is if this happens for everyone. I'm using a Nexus 4. It drives me crazy!
