Thanks first off to anyone who helps.My friend installed a new pioneer deck in my 190E and now when ever I shut the car off my radio station all reset.He can't figure out which is the memory wire.So anyhelp would be much appreciated.

 

year model?

 

1991 MerecedesBenz 190E 2.3 Thank you very much!

 

oh... i missed to read pioneer.

it means it's not becker anymore.

there are two wires with power on that area.

with ignition off, 1 wire still retains the voltage called terminal 15. that wire is for the constant feed to the radio to retain memory.

with igniton on, there will be two wires live. that second wire is terminal 30 or R. it feeds the radio for operation.

just connect the right wire to the right place on the radio.

 

Thanks alot just for your quick response!Thank you very much for the information,I will reply tomorrow and let you know how it goes.

 

Swap the red and the Yellow wires. Yellow is usually constant +12v (for memory), and Red is the Ignition 12v.

 

Thanks alot for all the help much appreciated! Very helpful website with cool members!
