I would suggest a Autocom bluetooth adapter #1273 and a stereo isolation cord part #1314, Here is how it works......
1. pair the zumo with the autocom dongle (make sure the zumo is in the mode so that the audio from the cell goes only to bluetooth when the phone is on)
8 NOTE THE DONGLE GOES INTO AUX 1 AND IS POWERED BY THAT PORT
2. pair your cell phone with the zumo
3. run the lead 1314 to the primary input of the Superpro avi (2 or 3)
How this will function: By configuring the system this way it will function like this.
A: When playing the mp3 on the zumo, navigating, or using the xm radio on the zumo all functions will come out of the normal hard wired port on the zumo into your autocom, when the phone rings the zumo will mute all of these functions and show you the phone call information on the screen.
If you chose to answer the call the autocom will mute all other inputs you may have (radar, zumo audio, etc) but the cell call will come through the bluetooth dongle and you conversation will function normally.
Call me if you have other questions.........I am Autocom Dealer and would be glad to help. Kieth 918-446-2245 emial [email protected]
