Superb mk2 columbus MDI only AUX

[Massline]

Hi all, hopefully someone might be able to help

 

i just got a superb mk2 elegance 2.0tdi 140 bhp estate with every toy except the power tailgate. 

 

I have a columbus head unit and an MDI socket in the armrest. On the head unit the MDI button only shows up as AUX and if I connect to the aux socket I get music from an iphone.

 

my question is I thought the MDI would allow me to use my iPhone for music and be able to control on the headunit but the socket is only charging the phone and not registering it on the Columbus

 

any help would be great, it seems the mdi is not working right

 

Thanks

Sounds like you're correct.

Press the "Media" button, do you have MDI in a greyed out box on the top of the screen (next to HDD, SD card etc.)

The MDI box is not greyed out, I can select it but it inly allows AUX as the connection available, very odd

[Rustynuts]

Have you connected your iphone to the MDI socket?

[Massline]

Yes, might be a dodgy cable but it does charge

[Rustynuts]

Could be a bad cable, could be a coding issue, could be a faulty MDI. Have you had a fault code scan done on the car? Have you tried a USB cable and device instead of an iphone?

I’ve got VCDS so I’ll check that first. Thanks

Any joy with this? I have the same issue with only the 3.5'mm jack working.  I have a 30 pin Apple MDI cable and it won't recognize it. Is there a menu item to switch between AUX and MDI?
