Thanks Pizzaguy! Yes it is the one I ordered and received even before the link that was posted as being wrong. It never said what it fit but in some of the questions/answers asked of the vendor, it was said it was an updated RCM for SLK320 and fits the Crossfire. As it turned out though, it was not the fix for my no start problem. Looks like it was a mal-adjusted RFID antenna ring. But before I start doing a "happy dance" I'll have to see if my no start condition returns. ( BEING 75 I HOPE I NEVER HAVE TO GO THRU REMOVING THE LOWER AND UPPER DASH! IT BEAT ME UP PRETTY GOOD TRYING TO BE A CONTORTIONIST GETTING TO ALL THE SCREWS AND DEALING WITH BRITTLE PLASTIC PARTS! )
