in a nutshell: car is a 1990 190E with stock alpine radio. I changed the battery today. then I started the car and punched in radio code. silly me, thought this would be a breeze, as I had done this before. but no, I messed up, and only after many attempts did I read the radio manual. I should have read it first, but I thought it would be a breeze (I think I read the manual last tuime).

okay, so I know what I did wrong. question is what does it mean to leave the system ON for one hour? do I drive the car for one hour with radio on and then punch in codes? surely I can't leave the key in the ON mode with radio ON for one hour! I'm gonna give it a go tomorrow morning, but my drive is only 30 minutes.

I disconnect the battery after evey infrequent winter drive in my 300SL.

Forgot the code was well and after three trys it started flashing 'wait'. Had to drive the car a few days later, must have been 45 minutes, before the 'wait' changed to 'code' and then I could enter the correct one.

This is for Becker radios. Not sure if its the same for the Alpines.

If an incorrect code is entered, the prompt “CODE” and the four stars are displayed again. If an incorrect code is entered three times in succession, the prompt “WAIT” is displayed and the radio is locked out for approximately 60 minutes. After three more subsequent incorrect entries, the radio is again locked out for approximately 60 minutes.

The lock out time will only count down if the radio switched on.

okay, I'm getting a bit desperate (not there yet, but...)! after reading the archives and the tips I got here--thanks, guys!--I drove car around with radio on to add up the 1 hour I need to redo the radio codes. this was not a single drive adding up to 1 hour, but more 15, 30-minute drives with radio on. after what I think added up to 1 hour, I entered the codes. first I input the first # and waited for CODE to disappear. it didn't! so I just entered the other codes and the error beep came on after the fifth #. what am I doing wrong?

do I need to leave radio on for one continuous long hour? I have the alpine radio without the WAIT message.

yes, I do have the original codes printed on the two credit card thingys.

you DO NOT have to DRIVE the car. Just leave the key in position 2 for however long it's required. Mine is only 15 min.
