My wife, Renata, loves her 1994 E320. It is "smoke" which is light gold to me.
I just replaced the Becker Radio w/ a JVC KD-HDR60, state of the art. NICE!
I did a lot of research. If you're doing a 94-98 E320 radio install, I hope you can benefit from my research and experience.
I prepared a 1 page pdf on my installation experience, with pics, parts needed, prices and where to get it all. I posted it on my account at 4shared.com. That was the only way I knew to get my pdf on the www. If you have any other ideas of how to post it, email me at mac26s at yahoo dot com.
It appears that this install will work for other MBs, VWs and BMWs per www statements. I quoted those statements in my pdf.
The link is: 4shared.com - document sharing - download RnR_E320_Radio_995.pdf
When the page opens you have to click "download" and then "open". The pdf will appear. I trust 4shared.com. If you do not, just skip it.
