CR-702 radio code.

Right, here's one for the radio buffs. Had a little work done on my Bargain-basement chariot yesterday which meant disconnecting the battery; re-connect the battery, code shows on the radio panel, go to the service history for the car, find code, insert code to radio, EEE - WTF??? Try code again, same result, three e's; remove radio from car, take lid off, locate diodes, note numbers of missing diodes, re-assemble radio, open radio de-code package, tick diode boxes, hit calculate - WTF again, it's the same code that I had already input! There you have my problem; a unit that, prior to disconnecting the battery, was functioning perfectly well; on re-connection, even though I have plumbed in the correct code, it comes up with the dreaded EEE. What do I do now? I mean, aside from the obvious one "buy a new unit", does anyone in VOC land have any experience of this problem? I feel a bit like The Waco Kid - awake, but very puzzled! Regards, C.A.

EEEE means you have input an incorrect code three times or more . To get around this you have to leave the radio on for a while then it will revert to CODE . The time you have to wait can be from 10 minutes to overnight depending on how many times the incorrect code has been entered . Is this the first time the battery has been off since you had the car?

Wotcher. Slightly missing the point - you get EEE if you input an incorrect code, which then reverts to code after approx 3 seconds; my point is that I have input what is supposedly the correct code (according to both the service records AND the diodes map) but it still throws up error. Yes, this is the first time I've disconnected the battery since getting the car. Help! C.A.

it seems the radio has had it then :-( i have seen this happen before ... a good time to upgrade to a CR 902 with RDS ! very cheap vie E-bay ...

That's what I was after, a bit of knowledge. I take it when you saw this happen before no amount of "code wangling" did any good? C.A.

no i gave up , still got the radio in the attic.

Well bugger me sideways and call me Grandma! I swear that Qi is right, we know a great deal about naff all! Decided to give the CR-702 one last chance before it went in the bin, key* in* the* code* - NOISE!!! I don't know, maybe it just wanted Christmas off, who knows; means I got music until the harness tail arrives anyroad. As Arnold J (Ace) Rimmer would say, "Smoke me a kipper, I'll be back for breakfast!" C.A.

CR 702 EEE code 

Hi, I know this is probably a bit late to reply to this thread, but I have only just joined. The way that I 'unblocked' the EEE message when I got it, was quite simple really. I left the radio OFF (capitals for emphasis and clarity - not shouting) for 3 hours then when I switched back on it was still there -- but wait, I turned it off again without touching any of the numbered buttons and then momentarily removed the battery positive terminal and reconnected it. When I switched it back on again 'code' was displayed and I entered the code correctly resulting in a perfectly working radio. Now, can anyone please help me with my problem? I've got this radio fitted in a 240GL 1990 (estate) and I want to know how I can remove it from the fascia in order to service it (belts, etc). I know how to repair this sort of item but I can't get the thing out of the car.

Hi Guys, Although the code is correct it is misinterpreted by the micro. This is due too the fact that the diode matrix coding is o/c somewher in the radio. I CAN REPAIR THE UNIT FOR YOU. YOU CAN SEND IT TO CENTRAL SERVICES (IPSWICH) 188 SPRING ROAD IPSWICH SUFFOLK IP45NR 01473 725953 REGARDS MARCEL
