Just thought I would ask if anyone has ever purchased the teamset of these units? And are you happy with the quality? I am planning on using this with my Garmin Zumo which is Bluetooth. The price of these are $229.99US, which I think is a fair price for what you get. https://secure7.nexternal.com/shared/StoreFront/products.asp?CS=cardo&CategoryID=4 Any thoughts or alternative suggestions are most welcome.
