Just Wondering; I am considering a radar detector for my 996.2 and came across a multi-purpose product called - SmartNav 5r from App-Tronics. it is a radar detector as well as a Nav unit with Bluetooth connectivity. Does anyone have any experience with this product or know anything about installation issues? I am normally sceptical of multi-purpose devices but I could not help but be curious about how it performed. Having Bluetooth connectivity would be an asset especially when my kids are in the car with me! Unlike me, they are not happy with only listening to the sound of the motor.
