Query: Ok - must depend on your car's antenna

Tried the unit in two different cars.One was completely static - couldn't use it at all (Acura MDX), the other car was OK, but enough static to bother me enough to return it (Lexus ES300).All in all I think you're taking your risks on this unit. It may work great, or it may not - depending on your car.
