Hmm... ok, well I can see based on the price why Honda doesn't want to willy nilly replace Navi units ($5k????), but clearly the problem is somewhere in these components (made by third party manufacturers) and probably not in wiring external of the units. At least that's the best I can guess after hearing from a tech that he cleaned the grounds and even created new/secondary grounds to the battery and no change. The only thing that won't touch is ground issues inside electronic board/components, e.g. nav unit, amplifier... what else? XM unit?
