Hi everybody! I'm new to this site & perhaps this question may be a little overworked but I haven't seen an answer to my specific question. I've got an '05 SL 500, which I'd like to swap out the current radio (with CD & Nav) for a satellite radio with the same as original features(CD & Nav). I've read articles that stated that satellite radios were in fact available in '05 & were installed at port of entry. True or false?? Any suggestions as to who might have a solution?
