Radio fine until I use the cig lighter for GPS/fone charging etc when I get an hissing sound using radio.
Thanks

Its your charger. Cheap ones use a switched-mode power converter circuit that interferes with radios. Either fit shielding on the cable to the cig socket or use a different charger

Having spent 2 yrs having to deal with cheap chinese unscreened unsafe chargers be lucky it's just making a noise seen some blow up or smoulder.
