I noticed a small icon on the right side of the screen and upon clicking on it, it said - TCU Unavailable. Does anyone know what this means? The owner's manual does not mention anything about it....

 

Found out that TCU stands for telematic control unit. Apparently this module allows tracking of the vehicle. I am going to try to call the Acura Concierge and see if they can locate the car....

 

I'm fairly sure somewhere in the vehicle setup options this can be turned on/off.

 

I found a setting for track location and that is required for the Navigation to work (which was working). I saw the same icon today and not it says Connected to Acura Link. I think I was in an area where Acura Link was not available and hence got that error. Will keep an eye on it and see if this happens again....
