HAM Radio install noise help

[n7qpp]

I have a 2022 RAM 1500 and just installed the following dual band - VGC VR-N7500. Power is directly from the battery. I have a video so you here the interference noise. This is being generated with the truck in run mode and no engine running. I have tried the following corrective actions:

• add a snap-on ferrite with a wrap of both the power and antenna leads
• remove the antenna and the noise disapperas
• changed to a different antenna
• moved the antenna to different spots on the truck
• switched out the radio to a ICOM IC-208H-this is the one in the video.

No change

Here is a link to a video you here the noise
