Aygo 64 reg no stereo sound

[Chriss27]

Right so picked up my 64 reg car with 9000 miles from Toyota dealer, they kindly added new tyres / brake disc and pads all round.

Anyway on way home noticed there is no sound coming from stereo ( it’s the one with reverse camera) any ideas, probably just a wire. Dealer will fix it but if a Simple fix  I will do it myself. Tia

Turn it up !! The radio may need retuning, try a USB stick with a few MP3s on it

Well just got in car and sound cane on for 2 secs then silence, loose connection somewhere ?  Just to make it clear there is no sound for radio or Bluetooth

Pull the radio 2 connectors, a 10 and a 6 pin side by side unplug both and just plug in the 10 pin and test, someone may have pulled the rear speaker out of the car, had them in the parcel shelf or even an under seat sub and left the wiring behind
