yatour or similar usb, sd & aux adapter for SYMPHONY
 

Hi, I have a Symphony unit waiting to go into my car. I noticed on the back the it has ISO connectors (so NOT the big BMW 17 pin plug).

I know i need an adapter to plug it to the car. Thats not a problem.

I want to ad a mp3 playing device to the CD changer connection.

Something like this

The only ones that say "rover 75" are the ones with BMW 17 connectors.
Has anybody here tried to get a similar product to work with the 8 pin blue iso plug on the symphony units??

Can I just use any aux cable adapter which goes into the 8pin cd changer connection on the back of the symphony radio?

Or isn't it that simple?

Will something like this work?

Or a simple cable like this?

They are advertised as "vw skoda seat " or "fiat Alfa" but never rover 75

Any one here knows what the difference ? Is it not just 'if it fits, it works'?

@pruts3r - did you get any further?
