Just wondered if this would work in our cars?

It uses the 3 and 6 pins. Made by a company called Yatour.

Anyone fitted one or have any idea?

I would imagine so, I have just fitted a DICE IPod adapter to mine that is designed for a BMW/Mini.

The only thing that may not work to well is the MP3 tags as I dn't think the standard radio firmware in the l322 can cope with them.

I use one of these transmitters:

It works perfectly and also charges the phone.

I used one of these

Which benefits from having a bluetooth connection as well as a dedicated ipod connection. It has control of the ipod via the steering wheel, track up and down, will charge it, and I can receive hands free calls on my phone!
If you decide to go down this route, you need the BMWT kit, but only require the short ipod leads, most of the BMW's have the CD player in the boot, hence the BMW trunk kit, but the FFRR has it in the glovebox, so you don't need 4.5 meters of ipod lead! Yesterday I couldn't spell Engineer...
