GPS question.

Does my model 3 have a gps antenna or does gps rely on map data? Thanks in advance, Carter

I believe there is an antenna where the cameras are located on the top of the windshield.

I have a GPS question of my own. After a year of happy ownership, by GPS yesterday started marking certain streets with red lines. Is this some sort of traffic warning?

The answer to the OP's question is yes, there is a GPS antenna (there is no such thing as a GPS system without an antenna), and also yes, it relies on map data to show you the actual map and where you are on it, rather than just some latitude/longitude coordinates. Maybe what you are asking though is whether the map data is dynamically downloaded from the internet, or whether it is located in memory on the car. The street map data does ultimately come from the internet (cellular or WiFi connection), but it is only periodically updated and most of the map data is stored in memory in the car itself, so if you go out of cellular range you will still have the map data present in the car. The satellite view, however, is dynamically loaded as you scroll the map/travel to different areas, so if you go out of cellular range you will not get the satellite view (it will just look like a grid with roads on it).

Yes, those red (and orange) lines are live traffic updates.

Thanks. That must be from a recent software update.

Been this way. How long have you had your car? Could be during the last few months traffic has been so low it doesn't show much orange or red and you have got used to not seeing it.
