I didn't opt for the factory installed Nav system, but I want one after reading these boards I was considering this Nav from Pioneer: AVIC-N1. Its about 1600 bux, not installed. This is an all-in-one system, check out some of the specs:
6.5" Widescreen TFT Active Matrix LCD Color Screen
Fully Motorized Mechanism with adjustable viewing angle (50 - 110????) adjustment
Automatic Front/Rear display positioning
Touch-Panel Control with AGLR Coated Screen
10 character sub display with scroll (XM only)
New enhanced color GUI & Animated background images
Background images down loadable from CD-R
Widescreen 16:9 Aspect Ratio
Intelligent Dimmer Control
Dual Button illumination (green/red)
Picture adjustments for brightness, contrast, color hue, etc
Compatible with DVD-Video/DVD-R/RW/CD-R/RW/MP3
96/48/44.1 f.s. 24-bit D/A Converter
CD Text with ID3 Tag and Auto Scroll
New US & Canada Dual (East/West) DVD
Map Discs with 12 Million POI (excluding Hawaii & Alaska)
Advanced search, (re-)routing and guidance functions
RISC CPU for Navigation and Vehicle Dynamics display functions
Exclusive 32-bit positioning CPU
64M SDRAM
Flash Memory

The system gives some cool feedback on your car's performance including "G's" you pulled, accleration, gas milage and tons of other stuff.

Has anyone installed this unit before or anyone have an aftermarket nav system?
How would it intergrate into my BOSE raido/cd system already installed in the coupe?
