Yes! It fits!
For any newbees out there like myself, the GPS glove box with the molded in GPS holder does fit on my 08 RXT-X. For anybody considering it, literally less than 60 seconds install. To remove, lift the glove box lid. On the lip near the latch on the ski are two small tabs that hold the glove box in place. Gently press both tabs while lifting the same end of the glove box. It has a psuedo hing on the front end and simply lifts - out. Drop the new glove box in, pressing down firmly till the tabs click past the lip of the box assembly and your done.
If you already own the garmin-do it .... cool factory looking mod to your ski.
Note to SeaDoo: So why can't you make the install of the boarding ladder this simple? Huh? Really? You need to buy a metric tap set to install on top of the $250 plastic step from a dealer .... You couldn't mold in threaded inserts for a buck or two ... come on. How about a molded dimple to mark hole locations at least. :cheers:
... but I luv your ski ....
