I've used both the Garmin N-Route software, and the Mobile XT (formerly Que) software on my notebook and Windows Mobile (Dell Axim) respectively. Unfortunately, they only work with Garmin units (verify to the device serial number.)

It usually has more to do with the software you're using. I know from different programs (MS Streets and Trips, DeLorme, Garmin N-Route, etc. ) there's usually some delay. My Garmin software seems the best for screen updates. Older Microsoft software used to update every 15 seconds! I think the new versions have either 1 second updates, or are possibly programmable. It usually doesn't have anything to do with antenna location, unless you frequently lose your satellite lock.

Has anyone in colder climates had problems buring out hard drives? I don't know if it's old skool or not, but we used to warn against condensation build up on the hard drive platters which would crash the disk (when the disk goes from below freezing to over 100 deg. F.) I'm probably going to wait a little while for the new "flash hard drive" that Sandisk is working on.
