This is my first post so please be gentle with me. I live in the UK and drive a MAZDA 3 5 DOOR HATCH 105 PS SPORT NAV 2016, Firmware version 56.00.513.EU N. I have just noticed that if I turn the rear windscreen wiper on the DAB radio loses its signal, when I switch the wiper off the station comes back on This happens 8 times out of 10 Any help would be appreciated Thanks very much. Ben

short in the wires causing electrical interference when the rear wiper is activated and electricity is passing through the circuit/wires would be my thought, your going to need to remove the trim panels near the antennas and wiper arm/motor assembly and inspect the wiring to make sure they are not somehow touching or have missing rubber shielding around them that would allow electricity to get out and cause localized interference

Thanks for your reply, I wonder if this problem is covered by the manufacturers warranty?

if the car is new enough and you have not made any mods to that part, I do not see why it would not be. if your dealer is not like the one by my house you should have no problems. cant hurt to swing it by, give them the details and ask if it is a warranty-able item to fix
