Range told me the Pulsar LT wasn’t working on the ‘21+ yet. Did you get it to work on yours?
I do not have a 21+. I just got the info from forum member slowride77. May want to message him and see what he has to say.

I'm totally new, and just pulling this out of thin air, but it sounds like active noise cancellation. I'm not sure if yours has it, but it could literally be your sound system generating that noise. Could be malfunctioning or it could be working properly and you are just sensitive. Just a thought.

I am surely very sensitive in term of accoustics/noises. But it starts only when the vehicle is moving. I don’t know how the ANC is working but even at speeds like 3mph I can hear it. When I stop it’s gone… go figure.

Try folding in mirrors in to see if buffeting stops

My 2021 Tahoe High Country is not near as quiet in the cabin as I hoped it would be?? I get lots of “rumbling” even at low speeds. The cuts in the payment seem to be amplified? It feels like it has 100 lbs of air in tires, but it doesn’t? Bridgestone tires and PSI is 34-35.

Anyone figured out what can be done to quiet down the ride?? Thanks in advance.
