4x4 mean 4 wheel drive, it could be all time 4 wheel drive or u can engage into 4 wheel drive, the vehicle have to be equipped with that.

you need an AMI interface cable, and of course the AMI interface itself. You can check the options list of you Audi at myaudi.de, sign up for an account and register your chassisnr//VIN nr. You will be able to see the factory installed standard equipment including extra options.If you're lucky this cable will do:" Part Number: 4F0051510P

Adaptor set comprising 1x adaptor for iPod/iPhone and 1x adaptor for USB for the connection to the Audi Music Interface. The ipod adaptor cable provides power and intuitive control of the device through the MMI and multi-function steering wheel."

It will plug in to the glovebox, there is a connector in the back (although it should originally be in the centerconsole in some cars). Will cost you about 50 GBP or US$64.

If there is no AMI interface installed, you're out of luck and you will need to do the AMI retrofit, you will need these parts:

(1) 4L0 055 307 A - Media unit wiring harness
(1) WSK 014 720 - Installation instructions
(1) 4L0 864 981 E 6PS - Media compartment
(1) 4L0 864 515 A 6PS - Cover
(1) 4L0 898 283 - Spring set
(2) WHT 001 250 A - Plastic pins
(2) N 906 986 06 - Torx screw (for media housing)
(1) 4L0 863 269 4PK - Protective piece
(2) N 909 187 01 - Torx screw (for protective piece)
(1) 4E0 057 785 XX - AMI control unit

This will set you back about US$ 800, and about 5 hours work.

Good luck!

The standard gear ratio for a '91 Dakota with the 318 V-8 was the 3.55 ring and pinon. The 3.90 or the 3.21, or the 2.76 could be ordered as an option. However the most of the Dakotas, either the V-6 or the V-8 were ordered with the 3.55 non-locking rear axles. Also your truck may have had either the 7.25" rear end, having a differential cover that is shaped ( 8 sides) like a "stop sign". Most likely will have the 8.25" rear end, having a "more rounded" differential cover. With your truck being a 318 V-8 the 8.25" rear end was more common. Hope that helps.
