Hi all, I just have to share this with you!!!!!!!!1........... wow I stubbled accross an item where for £119.00 you can buy what they call a RCH+ RCH with one touch function module. When I bought the Z4 (Z4 3.0si) I was always a bit disappointed that you could only bring the roof down from the key fob by holding it continuously after opening the doors, and there was no option to put the roof up from the fob either.......and equally disappointed by the way once in the car you had to keep your finger on the roof up/down buttons on the centre console. I was brave and bought the above mentioned module and had it fitted myself in about 25 minutes. It came with easy to follow instructions, 5 scotch connectors and pictured diagrams. it only measures 25mm x 19mm x 12mm. I am no ace with car mechanics or electrics but found it very easy and simple to do.
Now I can lower the roof with the fob....just push the open button on the fob 3 times and it lowers the windows, lowers the roof and puts the windows back up afterwards ready to get in and zoom off. Leaving the car I can walk away and again clicking the open button twice followed by a single push of the lock button it now puts the windows down, roof up, windows up, locks the car and alarms it. Better still with the module fitted I can open or close the roof whilst in the car as long as it isn't over 15mph with a single push of the interior (centre console) roof up/down buttons. Previously you had to be under 5mph and hold the buttons for what seemed an eternity whilst trying your hardest to look cool ate traffic lights etc......
I'd recommend one to all Z4 owners and if you need to know how easy it was fitted etc....pm me. I will advise you anytime. You'll find the item at http://www.gap-tech.co.uk which also has 2 videos to watch showing it in operation.
Hope this helps and we'll all look much cooler with one fitted.
