I am wanting to upgrade to a Zumo from my quest 2. What is the benifit of the 550 over the 450, I don't need bluetooth or XM. Thanks in advance!

Did you know that Garmin has a website where you can compare the two side by side?

You've hit on two of the four biggest differences - the other two being that the 550 speaks the street names for the upcoming turns and comes with the automotive mount and power cable (as well as an AC adapter, but many never use that anyway).

The car cradle and power cable will cost you about $100 if you want to use it in the car without pulling the cradle off your bike.

You can use the M C mount between a M C and car and do not need a second mount.
I used the MC cradle, had a suction cup mount, made a power cord to plug into the cigarette lighter and bought a cassette adapter to get the MP3 and GPS prompts through the truck speakers. If you don't have a cassette player in the vehicle you could use a FM modulator. Note the inline connector on the power supply. Makes for a quick swap between bike and truck.

I powered the Zumo from the source under the left pocket on the wing. The power supply cord that came with the Zumo was long enough to make a second power supply for the truck. 2 packages of inline connectors and a fused cigarette adapter for about $12 did the job.

Thanks for the input. I have decided to go with the 450 and will probably just use the quest 2 in the truck for now.

Garmin is discontinuing the 450 model and replacing with a 660 model. You might wait a few weeks and find the 450 heavily discounted, as vendors are going to try and sell off their stock.

I agree with John. Unless you can find a 450 at a blowout price, I would wait for the 660. The 660 looks like a real nice unit, and less cost than a 550, with a bigger display in smaller size case.

I hear you may win a Garmin 550 here: http://gl1800riders.com/forums/showthread.php?t=199579
