Bad Workmanship ....
I have an Alpine Sat Nav in the Motorhome. It was removed from our previous MH and fitted in the new one. The Dealership were not keen on fitting a camera as they had no idea about how it connected to the Sat Nav and didn't want to make any expensive mistakes. I had a look at the cable that was put in by the factory and decided it maybe wise to let the professionals sort it out. They fitted a camera and when I went to collect the MH the picture was the wrong way round. Ie Not Reversed. They tried to explain that I would get used to it but I insisted it was fixed. Anyway all has worked well for a couple of months and just when you need it it packs up. Took the camera off to have a look if it was a loose wire and found it all held together with a mass of black tape. What an unbelievable mess. Looks like it needs sorting properly as its just going to be trouble. Anyway could not find anything obvious so took the back off the camera. Well lets just say I wish I hadn't. I thought the the external wiring was a mess you should see inside the camera. If I had gone to a backstreet garage to have it fixed it would probably have been a better job as it was I went to an Alpine Car Sterio Centre. Will see what they say in the morning. Glad I paid by card.
