bu-353 GPS highly recommended
I just got one to replace the dead one that came with MS Streets & Trips and it is so much better than that one ever was (even when working :)). It gets a lock typically within 30 seconds of leaving my tree lined driveway in the morning. On a warm start, it's got a lock long before my computer finishes resuming from hibernate. And it typically sees 7 satellites in my area when the old one usuall saw 3, 4 if I was lucky and 7 very occasionally. I found out yesterday that there are at least 9 that can be seen since it hit 9 - something I never saw my old one do.
My enthusiasm for having a GPS solution in my car is now rekindled since I can see it working well now it consistently.
Plus it's a nice discrete shape and color - not like the flashy transparent/copper/blue glow that the streets & trips one had. Since I want my final setup to be almost invisible to a casual observer (or thief checking the car out), that's a good thing.
