New 8120 what about apps and maps

Hi,
I am new to the sight. I had a blackberry 8100 but never really used it for more than email. I lost the PC with my bb desktop not long after I got the 8100 and never really did much

Now I have the 8120 and a bb desktop manager and I'm loving it! So I am wondering what apps are out there? At the moment I am interested in maps or GPS. I am so directionally challanged and heavily rely on my husbands car for his GPS if I have to go anywhere out of the norm.
Is there a bb app that will act like a car GPS?

Any helpful fun tips would be great for my new 8120
Thanks
Chrissie

Well there are a few options. If you want turn by turn, try Nav4All (free) or Co-Pilot (6month free trial last I checked.)

With the 8120, you will need an external GPS as the 8120 has wifi, no GPS. The 8110 has the GPS and no wifi. GPS receivers can be found at the Crackberry Store.
