I have a 2010 V6 EX, no nav but it does have the bluetooth already installed. Exteremely handy, but would be even better if it worked properly. The whole bluetooth system works except for the steering wheel controls. The car had the problem from day 1 and had I known it would take this long (going on 7 months) to figure out the problem I wouldn't have driven it off the lot; the problem is still not solved and the car goes back in again next week. BUT that aside, a properly working kia installed bluetooth system is very convienent.
