Nokia 6682 / 6681

I ordered a Nokia Wireless GPS Module when I ordered my phone from LetTalk. I have had the phone for about 2 weeks but the GPS module is on back order. Do many of you have one of these and do you use it much? Anybody use another brand? Do they only work with wayfinder or can you use it with other programs?

I have used a Garmin GPS with my laptop for years and really like it.
