I bought the dummy GPS antenna below... http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=5863345828&rd=1&sspagename=STRK:MEWN:IT&rd=1 ...with the intention of sticking on my CLK to complete the look of my COMAND install, however, upon doing a bit of playing around with it on the roof, it just doesn't look right, so I'm going to sell it. I paid £12.97 for it on ebay and its brand new. I never actually stuck it to my car, only placed it on the roof and walked round the car thinking "naaaahh". Could be a bargain for someone. Make me an offer above a fiver!
