Battery was disconnected, now no power to radio,cd, etc. code is 3.8 405 but buttons on unit only 1-6 with 7-12 when holding down button. All fuses O.K. and been replaced in case.

Also on manual is that dot between the 3.8 what's that about. No decimal pts. on unit. Help, please.

I have a 1993 Mercedes 300 SE and after I got the radio unlock code from mercedes the radio worked all day just fine. I started the car the next day and the radio had a E 3 message on the display when I...

I dont remember if that year had a theft lock system or not, but I am looking into it. disconnect the negative battery cable for ten minutes and that should get you back to where you can enter the unlock code again and use the radio.

Where is the button on the radio to turn on the cd player which is in the trunk

Let's see, the 98 still had a cassette player in the head unit correct?
There should be a button toward the top, far right, that says Tape/CD.
If the CD player has been disconnected, it may be necessary to 'reboot' the system to get the head unit to sync up with the CD player. Disconnecting the battery is the simplest way, but you will have to reset the anti-theft code in the radio and reprogram various memories (seats, etc) if you disconnect the battery.

How do i make the radio in my 1993 VW cabriolet work the guy i bought it from said you have to input a code but he couldnt remember what steps to take. i do have the code he wrote that down. what do i do

You can try this. It's for a Passat but it's most likely the same for all models that year.
1. Turn the radio on. "SAFe" should appear on the display.
2. Push the AM/FM and SCAN buttons. Hold them until the display changes to 1000, then release. If the buttons are held too long or accidently pushed again this will be interpreted as entry of an incorrct code.
3. Enter the code usung the first four station programing buttos. The code will appear on the display.
4. Push the AM/FM and SCAN buttons and hold until the display changes to SAFe. Release the buttons.
After 2 incorrect tries the radio will lock up and refuse any more tries. Leave the radio on for at least 1 hour and then you can try again. Same deal, 2 tries and then lock up. The radio does not lock up permanently.
This needs to be done any time you disconnect power so write it down somewhere and keep it. Any time you disconnect the battery or disrupt power to the radio, blow a fuse or remove the fuse it will have to be done.
Hope this helps.

03 vibe cd player will not respond

I blew a fuse controlling the radio, charging system, turn signals, heater fan, ,etc..this ran down my battery.

When I replaced the fuse, the CD player would not respond, but the radio worked.

I disconnected the battery for over 30 seconds, hooked it back up, and the time reset on the radio to 12:00 and the CD player works again.

Error 10 message on display screen

Same issue but pressing Power and SEL would not reset unit. Found solution. Once again disconnected the car battery. Removed the face unit from the radio base and then reconnected the battery. Replacing the face unit AFTER the power was re-established solved the issue. (Probably pulling the radio fuse rather than toying with the battery connection would have done the same thing.)
