This is a VERY sore subject for me right now. Hopefully to get sorted shortly
Put it this way..My Elite ORIGINALLY came with the Satnav system. At some point, some bugger took the Satnav/Cd/radio etc out and plonked in an aftermarket one....the wheel buttons did NOT work...nor would control of the trip computer.
I used the PC99-X06 and the wheel buttons now work...The trip computer still does not. The display works but only warning me of things...such as ICE BUT I can't reset the computer or use ANY of its functions. I'm convinced that a Omega with a built in SatNav/Phone etc system MUST have the original audio system in or simply the display will not work correctly. The only option, possibly, and hopefully this will be confirmed this Monday, is that the display needs to be swapped for an older MID.
That said, and this I suspect is important. Behind the radio bay are 3 connectors that bring wires from the steering column. 2 connectors obviously go in to the aftermarket headset. The 3 connector, in my case, a grey 20 pin connector, is empty. What on earth plugs in to it, I'm not sure but I suspect it was a further collection of wires that ran from the original audio system to control the display and heck knows what else.
In my case the right hand stalk was incorrect..again some bugger had stolen that also and it had no end control buttons...so I fitted the correct stalk INCLUDING the small 4 wired connector which should control the display and its settings. Come Monday, with an older MID fitted, hopefully I'll regain control of the display as a result.
I just wish to heavens that someone could confirm what the "empty" 20 pin connector SHOULD be doing....what plugged in to it, where did it go and what did it do ? ! If it originally had something to do with the display, hopefully our little play on Monday should bypass it.
Its been a right ol' worry to me.
