we have had our tst system for maybe winter trips and always had an issue with the right rear not working at times. On the trip home in april this was the deal but I noticed the antenna had moved towards the windshield. The light went on in my head that maybe moving the monitor to the middle of the dash and not to the left of the steering wheel could help. No issues after that and not one issues coming south in Oct. I was thinking maybe a repeater would be needed after the forum guys were talking this about earlier. Nice to have in my opinion.
