I purchased an auto-dimming compass temperature uv mirror from Advance MCS Electronics. The mirror never worked and always displays "Errrrr". I have tried contacting the seller and they keep saying I have connected it wrong. Could someone please contact me with more info or what I can do to correct the problem? I don't think it should be necessary to calibrate the compass every time I start the car. The temperature also reads the temp much higher than it really is, it was around 60 outside and the mirror said 100.
Thanks,
Max Sanchez
