Right been out playing with my GSi tonight. Decided that I wasnt overly keen on the Kenwood head unit that was in there, so decided to try one of the spare CDR500;s I have sitting. This is where the problem lies.
Fitted one of the units and the stereo comes on but the MFD stays blank. If the radio security panel is removed it comes up on the top of the display saying "panel", however the lower section where the radio station etc. should be displayed is blank. Now I noticed prior to this that even when the old unit was switched off the lower section always stays blank (from memory the lower section should display the date when the headunit is switched off).
So did a little investigating and found that the wiring on the multi-plug is slightly different. The lower 2 sections of the multi plug are all wired, but the top section (the bigger of the 3) has 2 section not wired in which looking at the wiring diagram on the rear of the headunits is required.
Looking at the symbols one is marked DDL and the other has a pictue which looks like an umbarella on its side. Any idea if it can be wired with these units to work (as everything bar the display appears to work fine sound etc.), or should I look for an earlier unit?
Can post pictures of the multi-plug and wiring diagrams onthe rear of the units tomorow if it helps.
