Had the same problem with my hi bean install,
What I have found is that the subframe to mount the fairing is not grounded and the HID module is noisy electrically. What you need to do is make a faraday cage and ground it to the battery.
A faraday cage is a grounded enclosure wrapping the noise, in this case the HID module. I used a some thin conductive tin and soldered a wire to the outside and grounded it to the battery. Once the HID box is grounded the noise is greatly reduced. and the radio should work fairly well.
Another bit, make sure your wires going to the headlight ad not wrapped in the OEM harness routing is key. If routing will not solve the noise issue the wires will have to be shielded as well.. Make sure to use a singe point ground or all you will do is create an antenna and radiate more noise.
Hope this helps.
