Ran across this a few months ago but it wasn't released yet. It mirrors your Android phone onto the existing Nav screen so you can use your phone and most apps through the touchscreen. Would obviously be great for Google maps and music. Video,Audio Information Solutions for Toyota and Lexus (iPod/iPhone, USB, MP3, XM/Sirius SAT Radio, Video integration) Curious if anyone has this? It retails for $600 but it's still very new. Not a horrible price when you think all you'd be able to do with it.
Pretty much how I feel...hopefully more manufacturers integrate something like this into their products.
