Hello, I need some help as regards to this unit. I have not been able to find a service manual for this and I also am looking for the display as mine has started to die. The issue is it's so dim that I have to basically view it without lights on even after changing the dimmer settings and reset the unit. Either way if I can find an oem one that would be great or even a possible match to the screen that I can just swap out or soldier in either way the company is no help as they want me to just buy a new/upgrade saying mine is obsolete. This unit workes great still other than the display. Thanks for any help it's greatly appreciated.
