Mine's on order but not here yet I am supposed to receive it the week of May 4th. I will certainly post some information once I get it mounted on the bike and use it a little.
I still have a brand new in the box 550 (never used) that I need to get posted in the for sale area to get back some of the cash for the 660. :lol: I got the 550 at Christmas, never had a chance to mount or use it (winters in Cleveland), heard about the 660 in March and placed an order with Garmin using the AMA discount.
I like the larger screen of the 660 but is does lack XM, which for me is not a huge deal, since I already have a Sirius unit mounted on the bike.
A couple of folks on the Zumo Forums site have gotten theirs, and I think I remember Lamonster saying his should be arriving shortly as well.
GOT IT LOVE IT so far
Still working on the bike wireing I'm having to adapt my old IWay Kennedy wireing to work with the Zumo so I can still have my Sirrius radio too untill I can get the rest of the Kennedy parts ordered.
But I have been useing it in the car and it works great
