I recently purchased a nice CAS GNX-style dash with VDO gauges off ebay. I also purchased a VDO VSS for the electronic speedometer. I have the directions that came with the dash. I tried to install it on my 84GN but had trouble with the alternator not charging so I never got it on the road. I know the tach, oil pressure, water temp, boost and fuel level gauges work. The water temp and oil pressure senders are included along with the VSS. This is not a plug-n-play dash..electrical experience required. See Ebay#7983290763 for photo. Asking $510 ($430@ebay + $80 @ VSS). Shipping extra.
