Dct b101d

[BobMc]

This might be the root cause/problem associated with all of my Bluetooth/Nav/radio functions that have occurred over the last two months.
Has anyone else experienced this DCT?
How was the problem repaired?

Be safe.

Looks like you just need to clear the code:

There are a LOT of symptoms associated with the code--
the complete loss of the navigation system and OnStar are just two of them.

Thanks.
