Garmin Mobile XT DVD with City Navigator North America & nRoute Maps Software

I have the Garmin GPS 10 Deluxe which came with Garmin Que software. I evaluated the Mobile XT's last Beta version using Pocket PC version 5 on a Compaq 2495 and found the following problems. (1) It would freeze from time to time for unknown reasons. (2) the night view has gray bars at top and bottom of screen which I found to be too bright for night driving (the night screen on the Garmin Que was better in this regard). I pointed these out to Garmin but they just ignored me.
