True, especially bad on utes with crappy defroster antennas. Also I've got heaps of the cheap junk in my ute, so bye bye radio (don't miss it).
My dash cam is powered from the USB output of the cheap aux in radio cable I bought from ebay. I abandoned the aux in part, but kept the cable plugged in just for hard wiring the dash cam.
Also have 2 USB ports on the aerpro fascia I installed to upgrade the head unit when I abandoned aux in.
Lots of noise now.

If I cared about radio I'd planned to either buy a name brand USB stepdown (like from rs components or something). Or make/modify my own.
