What shall I do...?
 

I have a 420sel. Im contemplating on whether I should keep my stock HU and ass a CD Changer OR Replace my head unit with a MB Audio 10 HU and not put a CD changer. Which sounds more promising? Of course I can do the HU replacement myself if I decide to go the Audio 10 route since its mostly plug and play. I have stock speakers btw which are still good but typical 80's sound. How will they sound if I put the Audio 10 unit? Thanks

When I put an Audio 10 in my 420 I noticed a dramatic improvement in sound quality. Lots more bass.

Cool, I just looked at my stock system today. The PO made it removable and its called like a benji box or something?? Well anyway, I took the radio out and the radio cubby to see what wiring is there. The wiring is so different compared to my 560sel with no benji box and just a factory system.

Sura- Did you use the special harness for your audio 10? and did you do the install yourself? Thanks

I didn't need any adaptor. Mine was plug and play as it was. (Its a '96)

oh ok i though you have a 420sel but you have an s420 which doesnt need the adapter to use the audio 10.
