JLL:
1) I will be getting a Garmin soon. Porsche's Navi system is toooo $$$$
2) I think the Bose is great. Especially playing CD's The Sport Exhaust is better than the Bose!!
3) I waited about 7 months for my car, but this was by my request to avoid a Chicago winter and storage costs
4) I have the 19 inch Carrera Classics...and the ride is great No PASM
