It worked well initially but a few months ago the app would randomly stop connecting to the car. Audiobook playback stops shortly after the car starts moving. Voice-mail message playback plays while music, radio or audio books are still playing in the background. I have to pause whatever I'm listening to to hear voice-mail messages. It also drops the GPS app mid-trip. Google voice kicks in randomly during Audiobook playback. Voice->text message reply is often inaccurate. Several other issues.
