OK, I've hard rest again and only installed the Garmin-XT. It seems to be working just fine!! Awesome. However, when I fire up Google Maps, it can't find the GPS device. I've set it to COM4 and yet it still finds nothing. (Also, before this ROM Update, Google Maps used to allow you to select Automatic GPS Setup or Manual.) Now I only have the choice for Manual. What am I doing incorrectly, I never had to configure Google Maps with the previous V2 Rom. Literally all I did was open it up and voila, it worked.
And my HTC Keyboard doesn't work either.
