Default remote for cd471?

Philips CD-471 seems to have the remote sign in the display, looks identical to the 472, only the receiver seems to be missing..
Anyone knows if the 471 can be fixed to handle remote control?

Look at the CD473 r30 schematic for receiving the RC5 signals. MAB 8441 P/T146 and MC6805 L8.
Philips is known to programm differently their CPU and the last letters of the CPU signal the "firmware" included. So, if your numbers are different, you might not have RC5 decoding programmed in.

Found the 472 service manual, and that one is even a better fit!

1702 seems to be the IR receiver "OR102", what part do I look for, i have no clue!

The part number is DR102 (from Digital Receiver) and on both schematics is marked "1702", but now I see it in the listing as... " IR receiver BX1407; Philips part #4822 218 10212".
I would try any RC5 IR receiver.
