1992 300E sedan.

After sitting for a while, with battery disconnected..fitted new battery.....turned on radio...I entered the radio code, and I now have a radio that turns on and displays E ∃ then turns it's self off after 3 seconds and the antenna goes back down.:mad: ...you can repeat this action with no change.

Anyone know what happened?:confused:


.

So......I emailed Becker. They sent me this the next day.

Dk,
Your system is defective. Send in both pieces(head unit and trunk receiver) we will exchange them for $175.00

Please can you tell me what *E* *∃ * on my display means?

Have coded it, turns on, antenna goes up, but turns it's self off after
displaying this .

many thanks...dk

Sounds like a :deal2: to me!

That's the 1432 setup right? I have an extra HU somewhere from a 400E if you need it.

I have not encountered the display issue you are describing and I have seen many broken Beckers. :D Have you tried disconnecting the battery again? What about the alarm plug behind the radio?

You just reminded me:rolleyes: ...when the interior was replaced the radio was taken out too.

I'll have to pull it and check...thanks.:)
