HU code worked before, not now?

[ColdAccord]

MY e34 has a stock hu with a 6 disc changer. When I got the car, it had been in heated storage for a year. bought a new battery, put the code in the radio and it worked fine.

had the neg off the battery for 4 days while I did some work. put it back on, now the code doesn't work. I turn it on, it says "code." i put in "14642," same code that worked 2 other times before. it beeps on the last hit, so I know its in right.

any ideas?

Mine does that all the time, wait 1 hour with the key on, then try it again.

[ColdAccord]

hmm. any other options? I live in the city, can't really leave the key in it for an hour lol. also don't drive more than 15 minutes, maybe 20 tops at a time.

[Erik j]

hmmm. well try again in the morning. Mine would work some days and not others.

[ColdAccord]

hm. its been like 4 days, i've tried every day. weird

Your gonna need to try the hour thing. Time to go for a long drive on some nice back roads.

[ColdAccord]

damn. nearest backrounds are 30 min away

i wish i could smoke pot, then i wouldnt mind lol.
so just turn the radio on, dont do anything to it for an hour, and then it works for you guys, seriously?

Sometimes, it kind of hit or miss with my radio.

if you enter the code incorrectly 3 or 5 times in a row, the radio will go in "Lockout" mode, which requires the key to be on, for an hour uninterrupted. After that hour, you are able to re-enter the code correctly. I would double check and make sure you have the correct radio code before you try it again. PM me if you need any help.

Ive been thinking of wiring a small rechargeable 12v battery inline with the radio power so this doesn't happen to me again.
