Removing Standard Sony Head Unit

Hi,

Could anyone give me any ideas on how to remove my standard Sony tape head unit from my 97 Polo.

Cheers

Is it a removalable face unit? Either way there should be 2 holes at the side of the face or behind where the faceplate fits.

You should have got some small plastic lugs with the car when you bought it. these lugs simply pop into the hole and then you pull when you hear them click into place.

If you haven't got the plastic keys you have 2 choices.

1) Go to you local ICE specialist and ask them if they can remove it with their keys (this WILL cost you, unless your buying something from them)

or

2) Fashion some replacement keys from a wire coathanger/metal wire

hope that helps

Yeah it does have a removable face but I cant find any holes on the face or behind it.

I've removed my head unit XR-3759 (6n Polo) and put in an iso connector so I can run speaker wire for 2 rear speakers. But after putting the head unit back in... whenever I clip the face back on... there is automatically power to the stereo.
Maybe this is more useful than needing to click the ignition one or 2 notches... but being scared of it running my battery flat, is there a way to make it so that it requires the ignition to be turned back to 1 or 2 notches before power goes to the stereo.
Or can anyone give me assurances that without the face, there is no wastage of electricity running to the stereo?

Thanks!

You've got the red and yellow round the wrong way...... well right way for 99.9% of all cars on the road but wrong way for VW

God knows why they have to be different!!!

Thanks again bstardchild!
But if the wires are already wired up on the iso connector it means i have to cut and reconnect the wires up again right?

If it's the original ISO connector then NO

Well Maybe - I don't want you chopping wires about yet....

Buy an adaptor and swap the wires on that...... They are normally set up to allow you to swap them
I'll post again when I've found the wiring diagram I'm looking for

I'll try to find my wiring diagram key

I bought the ISO connector from halfords... its sold as a VW/Audi Audio Connector!

OK so does it have bullet connectors on the red and yellow wires?

If it does red goes to yellow and yellow goes to red

I've taken a look at it and looked at the wires. I think its purposely wired that way so I can switch on my car WITHOUT the key in the ignition. Might aswell keep it this way eh? It wont drain my battery if its switched off with the face in will it? (obviously I'll always take off the face, in which case is it completely safe from battery drainage?)

Originally there are 2 yellow wires from the ISO connector, why is that?

But on the ISO connector I bought from Halfords, it has the 2 yellow wires leading from the stereo end but one of the yellow wires goes off to the red wire.
Would I simply snip this yellow wire if I wanted the stereo to have no power when the key is NOT in the ignition?
