I am being offered a great deal on a left over 09 limited sonata with navigation. I have a couple of questions that might make my decision easier. I know there is no traffic with the 09 navigation, but is it possible to add a trafic module on this one? The map data is from 08. Is there an 09 or 10 map update. Finally I have read in this forum of some problems with this unit that required reprogramming. The software version on this car is V14. Is this the latest? Thanks for your help. I need to make my mind up by Sunday in order to get this deal. They are offering me $4000 off. So this brings it down to about $22500.
