No option to change from dark to light theme

Glad I DO NOT have Nav on my 2015 SLT
I use my Garmin for years
And use the Garmins in my service truck daily for many years and it never failed me !
Traveled cross country on my motorcycle several time with a Garmin !

On my Hyundai Elantra their system is also spot on

I tried Jimmy's advice and unfortunately it didn't work for me either. Still have the issue and dealer is no help saying that it's working as designed. They refuse to acknowledge the issue.

If you're determined to find a solution, you could learn how to use AlfaOBD to tweak the BCM.

There could be a solution in there but you will be exploring uncharted territory.

A successful connection will be a learning experience too.

@Ken226 has had some success.
