Hi,
The car has a Philips "Carin" navigation system as standard and the Empeg integrates just great with Aux-In, providing voice-over navigation!
I cheated with the install, I didn't need any extra cables and I didn't need to slice into my car wiring, instead I done the following .....
I spliced the supplied ISO connector onto the wiring on the back of the emped docking station, so it acted as an IN/OUT for power purposes, then I just re-routed the ISO from the radio through the player!
IDEA: maybe the docking station could have had both Male/Female ISO connectors, that way it could easilly be connected into most cars without the need for extra wires!
I'll try put some pictures and stuff up on a website real soon,
If anyone wants advice on installing into a 3000GT then I'll be pleased to help:
Cheers,
empeg@3000gt.co.uk !!!!!
