Stereo harness

Hi just about to upgrade my cd player. I have a 2006 MK2 I've been told I need an interface due to battery drain.
Would this be the correct item

 

[Legojon]

Could be wrong. But don't think so. It was some kind of canbus upgrade module.

 

[Harris1987]

I'll have to keep looking I couldn't find one anywhere

 

[Legojon]

Sorry I can't be more help. But I'm in the same boat. Got a 2006 Leon with the bog standard cd player. But can't upgrade it till the canbus is upgraded.

If I find anything I'll let you know

I agree with @Legojon I think it was a canbus module upgrade that caused the battery drain on the pre 2007 leon...

I think 2007 was 50 50 if it was bad or not... My 57 plate leon didnt have the issue

@Sharpy do you have buttons on steering wheel

 

[Sharpy]

I do. I used the connects2 interface to keep them working.

If I wasn't to use the control on the steering wheel would I need to upgrade the canbus

I messaged the seller of the original item I found and I've attached the reply still don't think it's correct

I very much doubt the seller will know about the pre facelift leon battery drain issue, did you look at the post I put up earlier? Or here for your reading needs..

It describes the can bus upgrades you should need for your car... All be it untested it gets you down a little further.

Will read it now thanks

That's what I've read too.

Mine doesn't have steering wheel controls. But. You can try an experiment. Plug something like your phone into the 12v socket with the keys out of the ignition. On mine, anything I leave connected (dashcam, phone charger), remains powered when I lock the car up.

This being the issue. Ignition live is controlled by the module. So it doesn't know to eg sleep the radio. Hence the battery drain issue.

The solution is more complex and requires the canbus physically upgrading and coded in. Which is why I haven't upgraded my stereo yet.

That’s interesting... looks like I’ve got lucky as mine turns everything off (like the lighter socket). Good to know though.

I put a rns 315 in and I don’t get battery drain, it’s a right pain to find the canbus and upgrade it so I haven’t bothered just means steering controls don’t work
