For those of you guys who can use the PX, I got a 550 thru AAFES last year for a good price during a sale. Don't remember how much but at the time it was at or below any other good deal out there.
Just installed the Garmin Zumo 550 which I located on Amazon.com for $675. By the time I added the XM antenna, I was still better off than the HD version. And the Garmin unit comes with RAM mounts for both bike and car.
Did add a special harness kit from cyclegadgets.com that allowed to hook the unit to the bikes power and also plug into the AUX port so I can manage the music through the Ultra's audio controls
So cool....used it during 400 miles of riding Monday and Tuesday
I have the HD Conquest. It's basically the same unit as the Garmin Quest II, but with more memory. If it wasn't for that extra memory I would gone with the Garmin Quest II. The reason?? The updates. The HD unit needs a special update...and there was a two year period from one update to the other. I don't know if the HD Zumo is much different from the Garmin unit or if it needs a special update or not. However, if I were looking at which of the two units to buy I would definitely check out the update issue first.
i like the look of the all black HD unit,,but really feel they are sticking it to ya to get it especially since you have to buy all the extras that come standard with the garmin,,,,guess i'll do some looking to see who has the best deal on the garmin...thanks....
