DO NOT BUY FROM THEM!!!!!!
There's a reason their so cheap. They like to do the bait and switch method of sales. They will call you to tell you you need to buy other parts or accessories for it to work on your bike. They also like to tell you that you'll need an upgraded model to support the other features.
I called them on the Zumo 550 and buy the time I canceled my order they wanted over $700. I found at Broadway Photo for just over $600, and didn't pull the bait and switch method.
IMO the 450 is a smarter buy anyway.....the 550 still requires additional equip to use the XM interface...which to me is useless anyway because the howling wind at mach speeds negates any chance of listening to music....save it for the cage days. And as for the MP3 player....my phone does that if I want to but then we're back to the whole mach speeds thing - pretty useless and to me it's more a distraction from what's going on around me, especially in town where the idiot drivers really seem to congregate.That's a 450 which were cheaper. No matter, wifey got it for me thru Amazon (but I'm still paying for it anyway!); was just sitting here trying to figure it out!
Jaysus - get the Nuvi 500 - MUCH better unit than the Zumo and it carries the same water/shock rating as the Zumo.My wife bought me a 550 through Amazon for Christmas and the screen was broke!!! She was pissed to say the least.......... she sent it back.
