Hi All,

I have a 2010 Update L320 TDV6 with the Harmon Kardon sound and I have an issue you may be able to assist with.

Note, prior to this fault, I did have my windows tinted, and they have advised no door panels or the like were removed so this is possibly a coincidence.

The morning after collecting the car, I notice that my radio didn't work, the touchscreen wasn't turning on and I didn't have any Bluetooth connections. I have heard the HK Fibre Optic means that if 1 part fails the whole system goes down, so i checked a few fuses and nothing jumped out as being blown (i think it was like 65 and 68 from memory)
I even pulled the touchscreen out and checked all the connectors in back to no avail.

2 days later when I could lower my tinted windows, I noticed my drivers door window and mirror controls were unresponsive. All other doors work, so again checked that fuse (ok) and did a hard reset to no avail.

At a bit of a loss unless it boils down to having to replace a component of the system. I have 2 weeks before i can get it looked at, any input from the brains trust would be advantageous.

Cheers
Jeff

Do you have IID tool or similar? are you able to check for fault codes?

How does the loom tube that runs between the door pillar and the door for the driver's door look - pinched or out of place? Give the tube a gentle wriggle to see if the door switches can be made to work in case there's a broken wire.
