Congrats on the new car. Your car has about the same milage and options as mine, so it gives me some idea of what my car is worth (though after subtracting the dealers markup, I'd get killed if I traded it in).
Anyway, the navigation issue you're talking about is with the screen - even if you upgrade the software/DVD, it'll be the same. The problem is that the resolution on the screen is too low - something they improved with the 2007 model, I believe. I've been trying to find a way to replace the screen without replacing the whole unit, which is a costly proposition, but haven't found anything yet.
Enjoy your new car!
thanks for your response. i just hope there's some way...later that we can change the screen for a better resolution. right now i like the bypass feature that you can't do with the newer models.
now that you mention the price and miles you got your car for i feel like i kinda got ripped off.. i just bought my 06 gs300 last week with a 3 yr/75k mile warranty for $33000 the only diff is mine had 26k miles and mine was black on beige :(
