Hi Dave, no I didn't. I have two Pro-164's that won't trunk. I had one sent back to RS 3 years ago and they "aligned it to factory settings" and I learned later on all they did was turn the tuning adjustment inside. It pulled out of tune last year some time and when I went to tune it the tune adjustment crumbled under my screwdriver. I just bought another Pro164 on Ebay. Put the same exact file in and no trunking. Played /w tuning screw and nothing. someone told me 164's are notorious for doing this. wish I would have known I'd never have bought the first 164.
I just bought a Pro651 on ebay yesterday. Problem solved.
