I am looking at replacing my single din unit with a double din sat nav unit. I have looked at retro fitting the RNS-E system, but is quite expensive at around £400. So i was looking at some cheaper alternatives. Looking on ebay i found these. Now they DON'T have sat nav, but they do say you can connect an external sat nav. Seems like you connect the GPS receiver through the video input, and put the software on a SD card. Anyone had any experiences of these, or know exactly how they work cos i can't work it out. I am awaiting some responses from the sellers as well.
