The new Garmin Zumo 660 will be on on the market by spring.

I figured I'd post this for anyone that is interested.

Thanks for posting that. I saw and ad for the 660 on Garmin's site but the link didn't go anywhere. From reading the article, seem to be a few enhancements over the 550 and a couple of things are dropped from the 550. Given the lower price, I'm guessing this is replacing the 450 in their lineup?

 

Went back to the Garmin site and the 660 is now up there. Looks like the only things it doesn't have that the 550 has is XM and holds only 10 routes instead of 50. Other than that, looks like the 660 has a bunch of additional bells and whistles the 550 doesn't have. If Sirrius (or XM) ever get around to making it possible to have satelite radio built in to the HK radio, won't need sat radio in the GPS.
