Please no laughing or comments about absent-mindedness or early onset altsheimers - I have already gotten enough crap from my wife...

So I bought a Nav Tool module so I could connect my Nav screen to a reverse camera. After I bought it, I got busy and when I finally got around to installing it, I looked everywhere and it was MIA.

So I bought ANOTHER one. Installed this one with the help of some friends and of course, about 2 weeks later, I found the first one. DUH.

I posted it for sale at HALF price..no takers for a few months and a nice guy popped up with an E46 and wants to buy it. GREAT! Look for the box, find it and the power cables, BUT no "VGA" cable - or what they call the RGB OUT cable.

I call them up and they want $75 plus tax and shipping for what looks like about a $5 cable..again it's a 9 pin cable that looks to me reminiscent of the old VGA conputer display cable.. link to install pdf :http://www.navtool.com/manuals/navto...ite%20copy.pdf

Question 1: Can someone take a look at the installation spec sheet link above and advise if there is anything special about the "RGB out" cable OR since it's a 9 pin cable, assuming I can find another compatible 9 PIN cable/plug, is there any reason to think it wouldnt work...?

Question 2: I must be missing ANOTHER cable. There is a picture of a cable with Blue connectors on the ends. Is this something special or is there anything else compatible for less..?

Description from installation guide:
PLUG&PLAY HARNESS: UNPLUG MATCHING CONNECTOR FROM NAVIGATION DVD ROM IN TRUNK, CONNECT NAV-TOOL MALE CONNECTOR INTO NAVIGATION DVD ROM IN TRUNK. CONNECT FACTORY MALE CONNECTOR INTO NAVTOOL FEMALE CONNECTOR, CONNECT 9 PIN CONNECTOR INTO NAVTOOL INTERFACE

I'm feedling bad since I promised it to a fellow Xoutpost-er and I am missing two cables, but at $75 EACH, I'm almost better off giving it away, or auctioning it off on eBay "as is", but I do hate to disappoint someone from the boards.

Any suggestions are greatly appreciated...

Perhaps as simple as advice on what the cables DO based on the schematic/install guide, and alternative choices would be start.
