Just fitted the Modifry DCI. I've had an Alpine fitted since I bought the car so I have not used the factory dash controls at all.

I have noticed that all of the functions work as they should with the Modifry DCI fitted with the exception of the vol up.

I suspect that its not a problem with the Modifry DCI and it is the factory dash control unit which may be faulty.

Any suggestions/help appreciated.

Cheers
