How to fit an AUX socket?

I found a thread on another forum that suggests my radio tuner is OK to accept an AUX source and all I need is a cable from BMW Parts. I want to use my iPod Touch in the car as it will save me having to keep burning MP3 CDs.

Assuming the Sport has similar internal parts has anyone done this or know more about how its done?

the sport has a aux input at the rear of the centre console....think it is standard (at least my 56 reg HSE had it) Range Rover Vogue ‘17 TDV6

Gone: Range Rover Vogue '11 4.4TDV8, Range Rover Sport ‘59, Range Rover Sport ‘56

The RRS has a different system to yours.
Only know because have picked up a alpine systyem for mine that someone had bought thinking it would fit the FRR and it didn;t.

Might be worth looking at BMW options as likley to have same system.
