I have been using my 753 for the last few years without a display (BOSS). The last owner had a problem with the unit and pulled it. I have had it in a box for the last two years. I decided to plug it in the other day and yes it doesn't work, once more it has been taken apart and the display is missing! OK, what to do. I am sure if it is available it will cost an arm and a leg. Has anyone just converted to mechanical display? Doing a search I did find one thread on the subject were the topic was discussed but didn't indicated that anyone has done it. Seems to be quite do-able as long as I would want to dig for the senders that might need to be replaced. I have one contact for a used parts guy that I think I will try. Plan there would be to replace the display with a used one if I can find one. The label on the back of the display says Vehicle Monitor, Gen 2, with other numbers... 00049518 CPN: 6665923 9711192530637 70385 Any of those sound like a part number? Thanks, Aviator
