Hi,
I'm looking for the circuit diagram of the dual display unit on a '92 Mk3 Astra. The original Phillips radio was swapped for a Sony CD player. I've read in this group how to permanently display the date while retaining electric aerial functionality, but I'd like to experiment and build a circuit to display other basic information when the radio is on (i.e. when the date is blanked).
Any pointers appreciated please.
Cheers, Brendan.
