to order the MyGig (Code RER) you need to order the electronics convenience group (code AFC) which is listed as not available with code DEC which is the code for the 6-speed.
I see two different entries for RER. One has a W/AFC next to it. Is it possible that the MH/AFC you're seeing is only for that particular RER? Perhaps the order entry has two different prices for RER depending on whether you have already paid for AFC. To get the cheaper RER you must have AFC. Am I making any sense? I'm just guessing!
