I prefer mine electronics free - less interaction with my radio equipment...
As all the electronics are in the box under the driver's seat, would it not be possible to isolate them with a Faraday cage arrangement?
Not just the box of electronics Tim - it's all the associated wiring and signals it carries - potential (and known) interference in both directions i.e. to vehicle and to radio kit...
