check in the Audio/Electronics section (under "General Corvette"). Do a search over there, there have been several write ups on NAV unit installs in the C5. There is also a C5 audio FAQ that may have what you are looking for. Congrats on the Vette, jand the JVC. You wont be dissapointed with either (I have the non NAV version of the JVC unit...and a C5Z)
You will have to tap into the harness on the instrument cluster. You need to find the Green/white (A7-circuit 817) with a tan/white (A6-circuit 33) above it and a black (A8-circuit 150 ) below it..The other green/white (A10-circuit 357) oil temp has a blank and a gray on each side.
all of the above is accessible from the drivers side knee bolster area....
You may also need the Databus wire..Im looking too
