Yeah I've taken a tuner list one out. The dash lights up but the message to enter code doesn't appear. I thought a few people on the site had changed from tuner to update!!Did you originally have an Update List HU in your car?
As you cannot swap between Tuner List and Update List...
If not, then the unit will probably be faulty. Or you have not connected the screen/stalk plug back in?
That's a shame Lou, if you want to you can send the cable back for a refund. PM me if you do.
No they use a different system.
So cannot swap between them.
Shame

If not, then Matt black offers a code service, think its stickied somewhere on the forum. (small fee to charity)
