And I run more radios in my truck than most, I have a commercial vhf, cb, HF ic 7000, and a ham vhf tmd-710a. And I have had no issue at all. How you mount the antenna is far more important than how you wire the radio. An improperly mounted antenna can wreak all sorts of havoc on the tricks computers, worst of which is common mode current, which essentially if transmitted rf coming back on the outside shielding of your coax. The most common cause of common mode is mag mounts, they just aren't adaquit, remember that your truck is essentially the other half of the antenna.
Take a look at k0bg.com for more info, he is the mobile radio guru.
