Second you will need this cable:
So you can fit the wiring loom to the ISO connection of the original radio/speakers etc.
Most important of all: you will have to know where the I-Bus (or K-Bus) connection is of your car. The cable is behind the original radio, it's a white/red cable with yellow stripes on it (Thanks to Keith
)
Just connect this cable with the iso adapter, I thought it was pin 17 of the connector
(Keith, correct me if I am wrong. I wrote it down on my work, I'm at home right now)
I recently succesfully retrofitted sat/nav in my R75. I can recommend Kufatec to everyone. You just can order the wiring loom how you wan't it. I ordered it with:
Monitor
MK3
Television
No telephone
CD-Changer
BM24 radiomodule
I replaced my CD changer with one from BMW, cause the wiring loom was prepared for that. That because the connection of a Rover CD changer is different.
