They are all IR types as far as I know. I've never had a problem with them tbh. As it's IR you know it's got to be line of sight and the sensor is right by the interior mirror, shoot from the hip, point it in the direction of the mirror without a pillar in the way and it'll work every time.bub2006 wrote: ↑Sat Jan 01, 2022 10:32 pm Do the later 405s have the little IR sensor near the rear view mirror or have they got the radio frequency type? The early IR ones I found pretty pointless as you had to pretty much be stood at the windscreen. Had the IR type on a early clio and a zx. I'm sure another car had the similar style but can't remember what. I'm thinking my early 406 may have been the IR type too.

All I need to do is get one of them working and copy the pulse to one of these. Someone at college had one years ago. The VCR player had a random fit one afternoon, it was as if it was possessed and the lesson got cancelled, wanted one ever since One of those watches also got someone a lengthy prison sentence too in days gone by...
