For what it's worth, I set my garmin to intermediate driver instead of the com ports, and it worked. And it seems to do nagivation just fine without being slow. So maybe for those of you who have experienced problems, give that a try.
Another thing is, this may have been posted already, but if you're sprint user, change the mms server add to "http://mms.sprintpcs.com" The default one wouldn't let me receive.
