I recently bought a Power Acoustik PTID 7001 NBT because all of the websites said it was navigation ready with the Navteq Navibox-1 unit, which was sold seperately. i found the unit, and bought it. Heres the problem... the navigation unit is has a 13 pin Din cable. There is no where to plug it in to the head unit. Is there another adapter i need or something?? ive looked and looked and cannot find anything. i was wondering if maybe plugging it into the cdc socket on the back might work...but wasnt sure how that would turn out. Plus the socket on the back is an 8 pin din outlet. I have found a cord that allows 13 pin to 8 pin connection, but i wasnt sure if plugging it into the CDC outlet would allow me to use the navigation system. What do you think? THANKS!
