My BMW Navigator VI is possessed

[Grumpy Goat]

I bought my S1000XR in October. I swapped my Nav VI over to it and have mostly ignored the RS. The XR apparently doesn't have TPMS(at all) or ambient temp going to the Nav VI (does have temp on dash).

I swapped the Nav VI back over to the RS yesterday thinking it would adapt and show TPMS readings. It did not. The dash TPMS readings took longer than usual to begin, especially the rear, but appear to work properly.

Is this normal? How do I get TPMS readings back on the Nav VI?

You did not mention whether the ambient temp reading was restored once you put the Nav VI back on the RS.

I would do 2 things in this order:

1. Clean the contacts on the back of the Nav VI and on the cradle
   
2. Reset the Nav VI.
   

Yes you may lose from data but if there is nothing wrong with the Nav VI then whatever telemetry is offered by the RS should come straight through the Nav VI, unmodified.

If that fails then you might want to try another Nav VI in the cradle and see what it says.

Could also be that the TPMS transmitter batteries are getting weak.
