Hello! Been creeping for awhile before I purchased my d3. Hooked it up myself after a lot of research and everything works great besides the speedometer reading on the unit. I hooked the VSS wire to the dark/green wire on my instrument cluster...I believe it was PIN A4. Does anybody have a solution to this issue? Besides that, I believe my nav would be good to go as well as everything else. Love this unit! Thanks or the help in advance! -Jason
