I posted this in response to something in the electical section, but thought it worth mentioning here in case anyone is looking for a good general purpose mounting bracket for 05/06 X:
"I got one of these for my Garmin GPSmap76:
Bracketron Linky Works great. Ironically, before I bought it, i had the GPS (clumsily) velco'd on that same exact spot just to the right of the steering wheel.
I can take some pics of how it looks on my 05 if you want. That location is ideal imho for a GPS or PDA.
www.myradiostore.com seemed to have the best price, and they included (free) some generic phone mounting hardware too (the PH-Mini 4) that might come in helpful. Had to call them to place the order as they didn't yet have the 05's listed on their website.
MyRadioStore linky I also got the one for my 03 X that I use for my Sirius Sportster."
