Good day all. I'm not sure if anyone posted this but I have a 2005 E320 and for some reason the radio constantly loses power and it will only work again after I disconnect and reconnect the battery. First I was thinking it was a faulty wiring but if that was the case there would not be any power after I reconnect the battery considering that whenever om lose power and disconnect the battery it comes on immediately after I reconnect thw battery. Also, I could drive for days or even weeks sometimes without issues then drive to the store and when i get back in the car there is no power to the radio. Any help is appreciated.

Try the W211 forum. You've wandered into the W221.

First, check your batteries – aux (engine compartment), main (trunk). BTW you should be posting here: https://mbworld.org/forums/e-class-w211-20/

Thanks, I didn't realize that I posted in the wrong place. I reposted in the W211 forum. But to answer your question, both batteries are good.
