I have a US 2004 E500 with Comand and I upgraded the firmware a number of years back to play MP3's with the help of this forum.

It appear there may be another firmware update but I'd like to confirm what I have. It seems since I did whatever upgrade that was I'm not able to get into engineering mode.

I've read the threads here on how to do it but I'm not having any luck, can someone assist with this?

Thanks,

Ray

This is what I compiled for my 2004 E55. Love to have anyone add information (especially for the empty slots)

---------------- May Lose Engineering Mode Beyond This Point ----------------
W211 589 15 22 00 Navigation updates the nav processor so that newer maps will work
W211 589 16 22 00 Headunit? mainly for improving performance and some bug fix, may add more SAT radio functions for newer models


I am at v22.10, since I used W211 589 14 22 00 to flash. (DVD MP3 rocks)
I cant figure out how to get in to Engineering Mode either now, hence this reply.


Thanks!!
