That is what I was wanting to do. Just don't know anyone close that has one.

Then select Accessory Test. This will list the accessories connected to the unit. If you don't see GPS as connected, then you need to check the connections or try your unit with a different puck. You may have a bad antenna. If you have your GPS antenna connected to an interlink, be sure its showing as connected as well. If not, then connect the GPS antenna directly to the unit and see if it shows up (you will have to turn the unit off to do this).

To exit this screen, turn the unit off.

Good Luck.

Thanks! The test showed unconnected. Was an easy fix, plug had worked itself loose.

Keep us posted on the progress if you would. I've got a 788ci. Good luck.
