I had mine fitted at a local radio come electronics firm for £200 my dealer said it could affect my warranty. When i collected my car the honda dealer had a civic there having sensors fitted. say no more!!!
Dealers!
All main dealers think they are so high and mighty, they all need bringing down a peg or two and a good slap is good place to start.
Much as I like my Jazz I have to say all the Honda dealers I've encountered have had the same pompus attitude.
Do Honda have a special course they send 'em on?
