Hi guys,

So I have a new issue, which I'm hoping is pretty simple. Basically the accessory socket which is located under the headunit has decided to not work anymore. When a device(car dvr) is plugged into the socket the power led indicator will come on for a sec, then instantly shuts off meaning I can't use said device. It's worse with my GPS plugged in, as doesn't show any signs of power at all.

I'm guessing this is most likely a fuse/relay issue?
It's just, I'm having trouble finding the fuses that control the front accessory socket. According to the manual pics below, The relay that controls the accessory socket is under the steering wheel to the right. I removed the 3 screws holding the front cover, and I've found the box it mentions but I can't seem to find how to remove the cover for said box to gain access to the relay as it seems to be a sealed unit.

Can anyone confirm that this is where the fuses are? Thanks.

I can't answer your exact question on relay location, but in addition to checking the fuse and relay, most accessory sockets also have a fusible link on the back as a backup to the normal fuse. If the relay is okay and the fuse is fine, next step is to check if you have power to the back of the socket. If so, the fusible link on the unit (often visible) is toast and you'll need a new socket.

Always check your fuses with a multimeter. Modern wedge fuses can look okay visually but not have continuity with a multimeter.

Thanks Fly boy for the advice.
I ended up finding the cause thanks to a work friend, After trying my phone charger and it working, We did alittle further investigating and tested my gps seperately to rule out the charger being faulty.
I recently had my windscreen replaced and didn't notice that one of my car chargers had been damaged and put in front of the passenger seat on the floor. Turns out a plastic o-ring from the tip of said charger was adding adding 0.5 mm of extra space in the barrel of the accessory port. Meaning when using a different charger such as the gps's cable it couldn't make proper contact to transfer the power through, but since my phone charger was alot smaller it worked every-time.
Thankfully it was an easy fix but would have been great if the person who replaced my windscreen had just stated he damaged the cable connector in the first place as it would have saved alot of time.
