Dension ICE Link FM Modulator & PCM on a 2004 Cayenne

[jen155]

Hi PH'ers

Hope somebody can assist.

I have the PCM 2.1 with Nav and Bose. As i dont have budget for a full Dension Gateway 500 system ive bought a Dension ICE Link Wired FM Modulator to at least get some tunes piped in from my iPod.

The unit has 3 x wires that need splicing onto existing wires on the back of the radio.

These are Black(Ground), Red (Constant +12v,Battery) & Purple (Switched +12v,ACC)

I havent pulled the PCM out to have a look yet but just wondered if anyone has already fitted one of these and/or whether the wires will be colour coded on the back to match ?

Any advice would be most welcome.

Cheers
Jenno
