Hey guys...yeah the AVC-RGB1 is actually out of production. There are some floating around though. I don't know what type of RGB Acura navi uses...but you could call Alpine and ask (the maker of the navi). Then it would be a simple thing of buying a converter that converted whatever signal you're trying to get in (composite, svideo, etc) to rgb. These converters do exist and are readily available but the avc rgb1 was the most well known. Someone call Alpine (www.alpine1.com) and I'll see if I can't dig up a converter for that rgb type.
