Here is the link to an interesting article that seems to indicate starting next year people will be able to display GPS info in the car from their cell phone using "terminal mode"
It takes about 10 years for enough of the cars being replaced before you reach what would be considered some feature being classified as common. The length of time to turn over a critical mass of th world's auto fleet is getting longer as cars become more reliable.
In another thread here we were talking about Wi-Fi and putting in a network in vehicles to use it.
I mentioned that most all of today's vehicles are networked anyway, all of the control devices being on the same hardware bus, & most all communicating on a CAN protocol layer.
All this might need is agreeing on hardware & software protocols, and addition of a 'gateway' device to make it work. Then it's simply (relatively speaking!) a matter of existing vehicle device firmware updates to get the vehicle to understand the gateway device.
Could happen fairly quick if the auto mfrs see enough dollars to be made with it.
Smartphones and smartdevices are really just in their infancy -- sort of the Model-T's of what they will be in 5, 10 or 15 years. I can easily envision autos being equipped with display technology that integrates multiple smartdevice features for both drivers and passengers (just as some already come with HDMI out to integrate with TV displays). Presumably navigation advances will be included/integrated as this evolves, so while the death of the standalone PNV isn't imminent it's not hard to envision them being redundant/irrelevant in the not too distant future.
hopefully its sooner than later.
