resurrecting a kinda dead thread but i want to be certain....
you swapped out the speedo cluster, but plugging it into the STOCK wiring harness, the speedo is still fully functional?
like, it registers speed correctly, and all the various lights within the trim above and below the screen cutout still work? im talking like fuel gauge, check engine lights, fasten seatbelt lights, etc.
with the same wiring harness that came in the non-nav-equipped stock car?
if so, that's extremely good news and i'm going to have to attempt something like this immediately....but with an android tablet
