I have a twin camera fitted by Marquis in Tewkesbury on a new van 20 months ago. Unfortunately, I have a failure in one of the cables .... (checked by swapping out etc). Note: two cameras = 2 cables but will discuss just one of them. The cable has a 3.5mm Jack socket to the rear of the van which the camera lead/s (fitted with a 3.5mm Plug) plug into. The cable then has some form of filter moulded on it before passes through the van etc to a 4 din mini where it enters a block along with the cable from the other camera, before emerging as a single cable to the clip on screen fitted to the mirror. Marquis as per usual have been poor with their service declaring its over a year old and the warranty has run out and you need an entire new setup ...... this just for a cable fault!!!. My question is does anyone have a similar setup (2013 van) and do they know where they bought it from, as Marquis don't know where they got it from even though the likelihood is the manufacturer probably offers 2 year warranty as many do. I have searched and searched but with no success. AS an aside they we equally unhelpful when the electric step motor failed and the step would not come out and wanted a min of £36 +vat to look at it to see it it was warranty claim. I got a motor from H Bowers for 28.75 +vat (see my post Thule V10 Step) and fitted it myself (even checking the aligment of the gears before fitting) in 22 mins!!! This are just two instances of a very poor service from Marquis since I bought the vehicle, so I'd never give them the pleasure of selling me a van again.
