Peace
I live in Israel, I bought a Silverado High Country 2500HD by personal import.
The importer in Israel does not bring High Country, he only sells LT, LTZ.
The radio in Europe works on slightly different frequencies, 90.0, 94.0 and so on.
Can the radio be calibrated independently? Ann yes how?
Another question, is it allowed to drive with exhaust brakes always on?
