Hi AMC


My 9c is fairly (1 month) new but I have the "older" version (short knobs, no chip update)

I was using the 3 knobs and one of them came off very easily. I lightly pulled on the other two and they also came off with no effort at all. Is there a way to hold these down better, or better yet can I replace them with the new taller knobs (what's the item #)? Would they still be loose?

Also, when its time to send the radio in for service and it is not under warrantee, would you still do the software update at no charge?

Thank you

Mike
