Just curious if you ever found a solution to fix the interference, or did you switch to a different brand?

It's the leds causing the RF interference. Probably a cheap non-CAN BUS kit. I have superbrightleds.com bulbs in mine and the radio is perfectly fine.

CANBUS LEDs in a non-CANBUS vehicle emit RF and that's what you likely heard.

CANBUS bulbs report to their control module if they are healthy (lit or dead) and they have a messaging system that is interrogated many times a second.

You prolly heard the LEDs calling to a non-existent mother ship.
