David is buying a new Chevy Volt car and it has an optional navigational package. It's about $1,000 and has an upgraded sound system. Is it worth getting considering smartphones have GPS?
There are pro's and con's to both options. The advantage to having the navigation system built in is that it will have a nice, big screen, and Chevy says Siri integration is coming. The disadvantage to it is that it may be more difficult to use, and updating the maps is cumbersome. It will require updating them through a USB stick or a burned DVD. Those updates can also be very expensive.
