My DCDC charger is interfering with my vehicle's radioUpdated 3 months ago

Relocate the DCDC charger and install it as far away from the car's radio antenna as possible.

Use a ground loop isolator to split the DCDC charger's 'ground' from your radio's 'ground'.

Ground the DCDC charger at a different point or directly to the battery to avoid sharing common ground with the radio. 

Ensure all connections are free of corrosion or other obstructions, as poor connections can also cause interference.
