Hope yer not offended. Things sometimes get overlooked. And sometimes those that have an answer donít get the opportunity to read every post. Iím one of the ones that donít have an answer for you but would suggest a couple of things. First would be to do a search for your question. The search is on the right upper part of your screen. Small icon of a globe and magnifying lens. Second, a lot of procedural things commonly arenít covered. A real help would be the CD for your SL. I bought one for my 400E from another member (Thanks again, Ross!) and when I get the opportunity to explore it, there is a wealth of information at my fingertips. You can get the CD from your local MB dealer, but the folks that run this board would love it were you to buy it from them.
Hopefully someone will come along to provide further assistance. Good luck.
