lilliput in-dash 7"
See this page, it mentions the wiring for the unit. You should really read through the whole thread, I appreciate that it's a long thread but there have been a number of problems with this monitor. Myself, Regal and Blackflux all have units that have failed and have been sent back. Hopefully yours will be ok. Post on this thread and also the thread below "lilliput in dash working or not" as we'd be interested to hear your views.
