Here's the thing, I could honestly care less about VHR's & the weather map.... Yes, I expect them to work because I paid for them but it's not ruining my life...
However, my suspicions have been that something is wrong with the radio, and for those who paid extra or went out of their way to get the truck with this specific radio, it's concerning. I personally passed on another truck with the 8.4 and some other things I wanted.
Also, in my experience when hardware is not properly supported, other things will have issues down the road, guaranteed... A lot of this truck is incorporated into that radio, reading these forum's has been incredibly helpful and I've discovered several ongoing issues with it, so I'm concerned for the longevity of the truck.
