AUX input

Have you tried pressing the button again to change from CD to AUX and then back again??

With engine on and the radio on, plug 3.5mm jack into mp3 player headphone socket and other end of 3.5mm jack into AUX socket and press play.
Press CD/AUX button, radio will switch to CD mode and display CD on the screen
Press CD/AUX button again and the radio should switch to AUX, display AUX and play music from mp3 player

Good luck

Try powering the MP3 device via the charging facility and the 12v lighter. I had a problem with a Creative jukebox that wouldn't give enough 'volume power' if on normal battery. Stuck the 12v charger in and it was fine.

It seriously sounds like a radio fault. It should come up AUX when you press the button even when nothing is plugged into the 3.5mm socket. If I read you right, you never see AUX come up on screen as being selected?

I'd first try completely powering off/rebooting the radio. Preferably by disconnecting the battery. (You do know the security code, don't you, for when it comes back?)

I had the same problem and you can tell if you have the prblem i have easily. Providing you have the CD/AUX button on the stereo, if you push PROG and then on the bottom row of buttons the > button you should get the 3rd option as AUX. This is where you can enable and disable AUX. If it is not there then you had the prob I had and a lot of other people seem to have that Seat don't apperntly recognise. You will need VAGCOM or a dealer to fix but all it is at some point the stereo has been re set and lost the code telling it it has an AUX.
Once you put the code back, works a treat! Takes about 20 seconds!

The code value is 4 (though I don't know where that goes, my mate with VAGCOM did it for me).

on VAGCOM:
Module 56 Radio
Coding 07
Long Coding helper
Will then bring up a list of all the functions available like this (just pinched off the net a MK6 Golf but will look similar on the Altea)



Click eat byte box until you get to one listing the above then put a tick in the Aux in box then close it then hit Do It on the coding page.

Might need a reset to recognise the turn on but cant remember how to on the Altea unit

Hi guys, dont mean to steal the thread, but didn't want to start a new on on aux input. I've found that on ebay, if i use it to connect to 3.5mm jack, will it play music, or some extra feeds are needed on altea? http://cgi.ebay.co.uk/Celsus-AUX-Qu...s_Cabling_ET&hash=item2559b92bd6#ht_947wt_905

Basically, my idea is to trick radio into thinking that it's cd changer. Will it work, or i need more than just wires?
Thanks

No,I don't believe so. That will work if you have the AUX on your stereo (the CD button has CD/AUX) on it. If so then great that is a simple version of what comes from the factory anyway and it works as the stereo knows it is an AUX and there is no tricking involved.
However if you don't than this contains no software to convince the stereo it is a CD changer and will not work as it will simply display NO CD.
(I could be totaly wrong and am willing to be corrected but that is how I understand it).

Sorry guys, kinda got lost at the VAGCOM bit. I'm having the same issues and have tried to resolve it by the methods that you have listed.

My mechanic has a VAGCOM machine, but not too sure if he knows how to select the AUX bits etc. Also I bought the car recently and do not have a code for the stereo.

Any advice?
