When I sold my e53, X5 I removed the Intravee kit and I understand it will work with the earlier FFRR, that use the BMW Mk4 Nav system. Hence it is up for sale.

For those who aren't familiar it is the best way to integrate an iPod/iPhone into the cars hi fi by using the CD player connections. Good music and plug and play.

On the X5 the Intravee can be used to set certain parameters; autolock/unlock, visual rear PDC, etc. but I don't know if it will do this stuff with the RR. Others on here, more knowledgeable in these matters, will be able to advise.

It's also had the "wake up" mod done so you can just leave the iPod connected for ever and not have to switch it on manually. The latest firmware is installed.

It has both length Ai net cables so you can locate it anywhere in the car.

Cost is £200 including postage.

Intravee kit is now sold.

No interest here at all so I guess this is still very much a BMW solution to iPod reproduction. 2017 5.0 Autobiography Supercharged

I paid an absolute fortune for mine when I had the BMW kit - in fact Dolphinboy has it all in his boot!

I even went as far as to go for the DAB kit too, but found the reception to be pretty terrible. 

IMHO £200 for second hand is expensive as a new Intravee is only £120 and a second hand alpine kca 420 can be bought for less than £30 on the bay of e.
Admittedly I'm a cheapskate as I bought the two for just £65 a few years ago...
