[OZAPRS] New wheels - dare I use anything that transmits?

I have just permanently installed my Kenwood TM-D710 into my 1 year old 
Mitsubishi Pajero SWB. I have been testing things before installing to 
confirm the effect if any of RF getting into the gismos.

My car is the "X" with all options and have not had one issue even when 
transmitting on 50W VHF or UHF.

I know your car is a diffent model but it is the same maker.  Test it first 
before permanently installing. I left all wires long enough to place the TX 
unit anywhere in the car if there had been problems.

I ended up putting the TX unit on the passenger site under the dash thereby 
needing very short coax and power wiring.

Hope this helps.
