Yep -- same here. Sounds weird, but I think it might help to practice a few typical scenarios if you're gonna be driving. Even if you are following all the obvious safety rules perfectly, you can get kinda wacky when the phone rings and throws everything into chaos if you aren't familiar with what needs to happen to either dismiss or answer the call. Especially wacky if you are doing 65 in Houston traffic... Like RaddOD suggested, sit on the couch, put it in nav mode, have someone call you and see what the best one handed way is (for you) to handle the call.
