so i called garmin today and got a bit of a result,complained about the ghosting on my 6,pre mlar.this is the 3rd one i told them not happy so happy christmas replaced free of charge,it was 4 months out of the 3 month warranty you get with a refurb.it may well go tits up again but the guy on the end of the phone said he was confident they have sorted the problem,time will tell.
