It's probably better to tell you what models it didn't come as most MB's have that option. For some reason, the R170 SLK never had an option for a nav in 2004. Just pick one up on ebay or from Steve the Euro pimp and install it. There's some instructions on my website as there are some harness issues to deal with.
