Hi - recently decided to swap out the hideous sat nav system that came with my CR-V. It was the Clarion one (solid state?). Halfords have struggled to find an aerial adaptor - the guy who fitted the stereo had never seen the aerial lead fitting like this. I've read somewhere on the internet that the clarion unit was a Russian unit that had been adapted. Perhaps this is the problem? Anyway, I'm into week 2 with a great new sat nav but no radio. Halfords are even starting to make noises about providing s full refund. I really don't want to go down that route so any advice anybody can offer would be great. Many thanks in advance.
