Is there a car radio that will mix sound inputs and play them at the same time?
AFAICT, both the Mazda 2 that I had and the current Honda Jazz/Fit and maybe any other car I've driven lately only allowed one input to the "radio" at a time.
So if I wanted to play the music on my Flashdrive, I couldn't get notices from Google Maps where to turn, etc. (Since google maps is not in the rental car, or any car I'll buy. It's only on the phone.)
And if I wanted to listen to local radio, via the radio built into the radio, I couldn't get notices from Google Maps where to turn, etc.
If I depend on the phone only, it's nowhere near loud enough to be heard over the music or talk. When I tried this at home, I often don't hear the navigation instructions at all, even though they are set on loud, and if I hear a voice, I certainly can't understand what it said.
The phone can be connected by bluetooth or probably AUX. I presume that won't make any difference.
