So far, not a single issue. GPS works great, IPhone control is excellent.
Tranfserred contacts, no problem
AM reception, is OK, FM is great
CD is great
Bootup time is about 20 seconds
I heard people complaining about the voice control, but so far this one has been perfect, especially on IPod. It will actually understand "play album Billboard hot 100 singles of 1998". so far, almost NO misinterpretations - bulletproof.
