Hey Thanx guys.
I am going to save my $1,600 and maybe get an extended warranty instead.
As for my blackberry, I do not think it has voice prompts. Personally, I do not care for it since I only use it for real time traffic maps. Its a Godsend in that department.
I use Google Mobile Maps which has the traffic. That can be downloaded to any mobile device as long as you have data package from your cell provider.
You could use Yahoo Go Maps too if you want. I think that too has traffic.
My Google Maps combined with Beyond411 with GPS is a perfect solution. I totally love it. Though Google Maps does give out wrong traffic info lately(have to email them to see what's up!).
Thanx everyone for saving me $1,600. I am still surprised at the price for just getting Navi/XM/Voice Prompts. They should have thrown in leather seats, 6-disc changer, fog lights to make it a worthwhile upgrade.
I don't have Ipod(can you believe that????

), but I will be burning MP3 CDs. I think that is a better deal for me since different family members are gonna drive the car. They can all have their own MP3 cds rather then buying 4 different MP3 players. (Playlists don't work cause my dad won't know what to do)
