So.... After contacting my dealer today I found out that this particular TSB bulletin it’s not actually for my high country. I guess there are different types of radios and this radio in my truck has not been addressed yet.
or maybe someone knows something different? I was really getting excited about the fact that I could once and for all get this fixed!
If anyone knows about any other service bulletins addressing this issue with 2019 high country’s, I would love to hear from you guys!
