I have an aging Passport 8500X50 that still works fine but does not have the ability to screen out the annoying TSR?s or traffic speed monitors that are becoming all too common on highways. Passport tells me mine cannot be upgraded to do this either. So I am considering a new one that has this capability.
Before I drop around $500 on a new model Passport I figured I?d ask if anyone else has a better idea or likes another manufacturer?s models better. If I believe all the write-ups it appears that Passport does not have much competition which seems hard to believe after so many years.
