Right now I have the Cardo G4 and ride on a Honda 08 silver wing 600 cc scooter.
As of next week if all goes well, I will be the proud owner of a 02 1100 with only 40,000 miles and looks new, with all the recipes, up dated-ed Clear View windshield and an up dated seat.
Best part is this guy is my size and weight so it fits like a glove, and only $ 4500.00
Any way, while on my scooter I use my Cardo G4 Blue toothed to my smart phone and a used, i-pod, from Ebay with 1500 songs, many free, from my library but my GPS is from Costco and only cost I believe around $ 125,00 that does not have that feature, which is OK because if I turn down the music, and GPS is turned up to loud, I can hear just fine, and does not cost hundreds more than a (motorcycle) GPS only because it is not water proof or shock proof?
I do use ear plugs and a modular helmet from HTC, I bought from LeatherUp.com for $ 180.00 which is much better, as far as air circulation in the summer but a little more wind noise, than my two the more expensive ones
