The upcoming iOS6 mapping will work for me. The existing (iOS5) Google maps implementation is a little weak, but with iOS6, the iphone, Parrot Evolution BT, steering wheel control harness, and Mediabridge ipod interface I'll have a full voice integration nav system (turn by turn nav, and voice control), as well as full MFSW controls, music, high res graphics, extended SIRI support for voice control telephony, texting, searches, apps, and a lot more.

I've also built the Parrot BT microphone (for BT phone and SIRI access) into the existing steering column mic housing - so between that and the SpecDock iphone mount, there are no external mounts, wires, or clutter that looks any different from OEM.
I like this concept of simply plugging in a new 'brain' and advancing the car's feature set exponentially ...
