Be aware, there are 2 types of CDC2 - one that works with CCR600/CCR800 type, and one that works with CCRT700. It seems the 2 are not interchangable. Also, the CCRT700 needs the special CCRT700 display, not that standard MID fitted to cars with CCR600/CCR800.
If you need further info, I can be found on the Omega Owners Forum (http://www.omegaowners.com)
