Suzuki swift sz4 2015.how to stop radio automatically coming on every time you start the car

can only be 2 things
lost power to radio (bad fuse, or bad radio ground)
radio dead. (time to upgrade?)
if not a stock suzuki radio, it can also be the hacked wiring
bad from installing that aftermarket radio ,

fuse bad, to it or just loose.
if not bad wire from fuse to radio
or radio bad.
or ground to radio bad, unlikely do to not forgetting time and stations
the radio has 2 power wires, main power, and memory
main power is the failure here.

if it goes dead, check for 12vdc key on, to radio power pin first.

rear of motor and a ***** to get to

the engine was flooded probly fuel regulator is bad

Timing belts don't while because they don't slip! Could be the water pump/alternator belt.

get the radiator checked and get the air filter cleaned and get the check teh coolant level. i ahd same issue in my swift. and it got fixed. just follow these.. it will fix the problem. no big issue.

Im afriad i dont have a solution, but instead the same thing has just happend to me. Does anyone know why? and how it may be fixed?

look on ebay for the radio removal tools. there should some slots or holes either side of the radio where you place the tools into the radio. then hey presto the radio should pull out.

hope this helps.

suzuki swift normally comes with two gas filters one underneath the bonet and one at the back underneath that one at the back might be clogged up or even the one in the bonet
