Hi, I'm looking to get an aftermarket CarPlay kit for my 2009 Mercedes CL 550. The only thing I could find is this here. http://www.navtool.com/mercedes-benz-cl-class-2007-2009-apple-carplay.aspx They have a video here and it looks functional. The reviews for this company tell me that I should probably look elsewhere. They are in line with the experience I have from talking to the customer experience that only responds to the first question in my e-mail and ignores the rest. Also, the website and their videos look extremely shady and unprofessional. But what's the alternative? Does anyone have experience with aftermarket CarPlay in a C216 or W221?
