TIFF-C20WTH, I had an S6 and it was crap.The satellite signal dropped out and stayed out more times than it was in.They replaced it 4 times and they all did the same.In the end I would end up watching the satellite count and not concentrate on what I was doin.Then I got nicked in october in warwickshire of all places (the safest place to be according to the pigs headed paper) by a camera van doin 69 in a 60.Snooper then replacer my S6 with an S4 and the radar/laser unit was replaced as well.Up to now (touch wood) I havent seen the signal drop out at all.Only thing thats gone wrong was yesterday when I was on a B road in the middle of nowhere and it said "warning gatso"?I was on a farm track rather than a B road.
