Gamma stereo won't unlock after flat battery - denty2005
I have the correct code for the stereo unit from my log book, but the manual tells me to press TP and TA simultaniously to enter the code. I don't have a TA button, and the manual unit differs from mine. I've tried all sorts of button combinations to enter the code, but can't seem to do it.

The car is a 98 passat, and the stereo unit is a Gamma model.

Anyone had this problem?

Don't know if I've got the wrong end of the stick but my Gamma manual states: -

1000 will appear in the display

Input the code number attached to the code card using the station buttons. Use button 1 to input the first digit of the code, button 2 the second etc etc.

then press either the search or the manual setting rocker switch for longer than 2 seconds. Then release the button.

The radio can now be used again!

Hope that this works.

If that doesn't work, also try disconnecting the battery for a while. A flat battery will often scramble it, especially if you keep trying to restart the car before the battery is charged.

Had exactly the same problem after recharging a flat battery. Gemma unit completely dead - no "safe" message, in fact no signs of life. Took Hamsafar's advice and disconnected and reconnected battery. First got the "safe" display which after 60 seconds changed to "learn". 60 seconds later, all back to normal, including the pre-stored stations. Major relief as I don't have any code number to enter. Thanks again H

I seem to remember the VW Gamma radio remembers the car it's in somehow. Had one in a Golf and Passat and battery disconnected to fit handsfree kits and definately came back on without a problem.

My Gamma stereo unit is the same. After reconnecting the battery the set goes into a check routine (Safe comes up on the display) and in a couple of minutes or so the status quo is restored.

PS

It's because it's tied to the actual vehicle - it wouldn't perform the same routine in another vehicle.

Which asks the question about the Gamma radio in the car of the OP... it should just work.

How does it know which vehicle it is in-must get a signal from somewhere???

It gets it from instrument cluster on later cars via CANBUS, I *thought* this only happened after year 2001. Vauxhalls are the same.

Well my Golf GTI 1.8T in August 1999 did this. And so did my 2000 Passat 1.8T.

I recently had a new engine put into my 1998 passat, and my radio now rejects the previous radio code.
Any ideas on what I need to do?

Won't talk to the ECU probably - it needs to matched through what Skoda call the "comfort" code.

Thanks Rob - it worked after I entered the code and pressed one of the seek buttons fro 2 secs. Turns out I have a Gamma 5, and the manual is a Gamma 4.
