After having my entire A/C serviced which resulted in a condenser and expansion valve replacement, together with a full-service cleaning of the evaporator (which means the shop took the entire dashboard out), I now seem to have a parasitic drain AND my speakers pop/thump and produce a very faint hiss when turning the ignition to ON position. I do have an aftermarket radio which I installed myself (so I'm 100% sure the wiring was correct) about 3 or so years ago, and prior to the dashboard removal, my speakers never pop/thump and there was no hiss at all.
Now, I've had to buy a new battery and decided to track down this parasitic drain. I've measured the drain to be anywhere between 50-60mA with the car locked, all doors closed, only the hood is up, left the car overnight to ensure no other module remains awake.
Took the fuses out while tricking the car was fully closed (had someone hold the door switch), took the fuses out and I found the 15A ROOM LP fuse, when removed, the current drain would drop to 10mA. Is 10mA standby current acceptable for this car or should it be lower?
For reference, my 2018 IS350 fully locked and asleep has 10mA standby current, even though that car has a remote sensing keyless entry. So, honestly, I think the i30's standby current should be even less.
Does anyone have the wiring diagrams please if you can share? I would very much like to track this drain down.

Anyone have the wiring diagram please?
Or where can I get one?
For some reason my country no longer has access to Hyundai GSW. So i can no longer pay for the GSW access
