Dash-cam

I bought a DX 1000 dash-cam for my Sperb. After a period it stopped working, so it was replaced under guarantee. This new unit also failed and was replaced with a third unit. Needless to say this also gave up the ghost. The problem seemed to be that the heat-reflective screen was preventing the GPS signal from getting to the dah-cam. Aguri said that the returned units worked satisfactorily, but failed to look 'outside the box', to establish why the units didn't work with my particular car. This is a warning to others who might be thinking of buying such a dash-cam. Aguri have been very good in replacing the units, but not so good as to establishing why they didn't work with my Superb.
