I bought a LG professional hands free car kit and there is an external antenna...i want it directly in the middle of the back as would be expected however that is right where the radio antenna on the 2000 max is all the way to the top and the guy said he thinks it might mess up the radio signal...any experience or thoughts???... bc i don't want it to be off-center... i think that would look stupid and i'd prob end up not using it. thanks.
