sorry to go off topic on this thread, but if you feel like sharing I'd be curious as to what you're plans are as I'm about to purchase one of the mentioned nav units for my titan.
Not sure what ClashoftheTundra had in mind, but I made a thread about my swap in the How-to Section. Others have done it as well, so search "nav install"
But heres a bump for the awesome deal on those navs
Im either going ipad2 if i can work with fiberglass... or if not im going 7" honeycomb tablet (no hard buttons, moved to touch screen) or the blackberry tablet. I should have those around the 22nd.
