Aux Jack Interference/Buzzing via GVIF
Hi all,
Does anyone have a part number for this unit? I can't find one anywhere

I've got interference when my aux cable is plugged in. If I wiggle it around in the port a bit, the interference changes, and sometimes goes away but when it does I have reduced audio quality (crackly sound and loses crispness).
It's always been a bit dodgy, but has gotten worse today after reinstating my GVIF unit (don't know if extra wiring in the car means more interference?!). My first idea is to replace this part as there seems to be some kind of dodgy connection...

Yeah. As soon as I plug anything into that aux port I get noise 2007 Porsche Boxster (987) 2.7

May have just found it actually... XVO500020... Anyone got any guesses if that should fix my problem? Probably worth a go for £10 2007 Porsche Boxster (987) 2.7

Do you have a USB adapter in the socket next to it?

I do in the front actually, but just pulled that out too and the problem persisted.. I've taken some videos of it, I'll try and upload them.

So... I've replaced the aux port this morning but unfortunately it hasn't made any difference to the interference/buzzing.
However... I've had a play with the GVIF unit and realised that when I unplug the input cables to the GVIF, the buzzing stops. Please see videos below...
Aux selected on radio, but buzzing only starts when I plug in the aux cable:
But when I remove the GVIF input cables, the buzzing stops (need the volume up!!)...
I'm faaar from being an electrics expert ( ) so any ideas where to start? I'm keen to keep the GVIF as it gives me reversing camera.

Had a play for a while yesterday and (unsurprisingly) can't work out what's wrong. Anyone got any thoughts? 2007 Porsche Boxster (987) 2.7

How have you connected the sound from the GVIF into the system?- have a read of this particularly page 13.

I think its a common 'fault' or if you like your LR's, its a characteristic
Mine is the same

Thanks guys.
Trying to understand the instructions as I didn't actually install it myself. Is it possible to just remove the audio part of the connection as I'm only using it for the camera now? 2007 Porsche Boxster (987) 2.7

In that case you just need to disable the AV inputs with the dip switches, take a photo/note of them before you start as they can be a pain if you get it wrong. It can when others can't,
It will when others won't,
It goes where others don't.
