Integration with car nav system

[Ross Myers]

I read somewhere a few months back there is an app for iOS that put the images of the phone's nav software (as dismal as it is) on to compatible multimedia type systems found in modern cars these days, sort of like a remote screen thing where you see what is on the phone screen is mirrored on another (all done via Bluetooth I assume). Unfortunately I forget what it was called, but does anyone know if such a thing exists for WP8?
TIA

audi and a few other turds have teamed up with apple to do this. Like all of these systems, I'm left saying "what happens when apple is no longer popular"? Never make a system that only integrates with one device.
