Peugeot 806 cigarette socket not working

If the sat nav is not responding to touch on the touch screen of your Peugeot 207 Sportium, there are a few things you can try: Check if the screen is clean: Sometimes, the touch screen may not work if there is dirt or debris on it. Use a clean and soft cloth to wipe the screen. Restart the system: Try restarting the sat nav system by turning off the car and turning it back on again. Check the settings: Check if the touch screen settings are correct. In some cases, the touch screen may be turned off in the settings, so make sure it is turned on. Update the software: If the sat nav software is outdated, it may not work properly. Check for any available updates and install them. If none of these steps work, it may be a hardware issue and you may need to take the car to a mechanic or Peugeot dealer to diagnose and fix the problem.

- Only to check those fuses again.

Something in one of the fuse boxes normally. Either inside the car or under the bonnet.

It's definitely a fuse keep looking

check your fuses cigar lighter and data link connector are usually on same fuse, if it keeps blowing fuses there is a sort somewhere

change the socket

Just buy a cigarette lighter socket and install it yourself.
Supply it from the vehicle +12V accessory power; don't forget to also connect 0V (ground) to the socket metal frame.
Accessory power is normaly used on the vehicle to power heater fans, radios etc.

Check to see if you have power to the fixture, make sure you have a good ground (fixture to dash tight), if all these check out you may have a bad fixture that needs to be replaced.

check the fuse in the panel, more than likely its popped. if not, the wiring to the socket may be bad.

I am not that familiar with peugeot's but. You can buy a test light for cheap or construct one if you have the parts. And most cars have a fuse box inside the car and another one outside under the hood.
At the least you can pull each fuse at a time and check if thier burnt out.
Also check to see if there's a foreign object (like a coin) in the cig lighter socket.
