Taking too long? Close loading screen.

Save Maps to Memory



Since the mapping app is web based, and due to the speed of the 3G, it take longer for the map to load. Most of us are using our car in a specific area, and just like in Google maps, an option to save the map to the device (car) memory would make the user interface much faster and smoother. This may be an easy fix (software upgrade), and maps, just like in Google, would have an expiration date when the user would have to reload/refresh the maps to deal with any potential changes.

I live in a dense urban area and use the maps mainly to check traffic.  On many occasions I find myself waiting for the maps to loads while zooming in or out or when starting to drive. This condition lead me to use my phone like I did when I was driving my trusty Toyota Tacoma. My phone is reacting so much faster than the car. And yes, I have 4G LTE and the maps are saved to my phone.

I wish Tesla will provide a fix so I can use this beautiful screen instead of my phone .


Tesla already does limited caching of maps, but it may require more memory than is available.  It’s also not clear how separate traffic information is from the maps – they may be bound together by Google.

Memory is cheap ... caching should be automatic and standard ...
This is extremely important for trips outside of cell phone coverage areas.
Does tethering help?
The sat nav becomes useless in a non 3g area .... Just when you need it cos you are travelling cross country or on a long trip and enter an unfamiliar non 3g area the map disappears. Needs to be in memory.

When the destination is entered and trip started the map should be downloaded then it is present for the trip. Delete at destination or after return leg.
It does seem completely bonkers to have to resort to using ones smartphone/satnav/paper map (FCOL!) when away from 3g - this is a serious issue in many parts of the world.  For the sake of $50-worth of extra  memory you could have the entire countries maps loaded and never have to worry about losing mapping again.  Better still, do a deal with TomTom!
My 2012 smarthphone (Nokia N9) is able to store all the car roads of the world for GPS use. This is great for use when no internet is available.  It costs a ridiculously amount of memory to store that: a few 10's of GB.

Is it implemented yet ?

Google has bought waze since then and memory in AP2 should be greater than before
This is a HUGE point, IMO.
There have been numerous times where I'm trying to on-the-fly redirect my route, or simply zoom in/out or pan the current route, as I'm driving through city streets, or about to get off the freeway, and I have to wait for all the gray blocks to get filled back in with map image to make a decision to turn or not.  It has put me in unsafe situations in the middle of traffic, where I'm forced to ignore the map and possible new directions just so I can avoid the traffic around me.

This is unacceptable.

We have 2 USB ports in the center console, and many of us use one of those ports for a thumb drive for music. WHY CAN'T THIS DRIVE ALSO STORE OFFLINE MAPS??

Just like our Google Maps, you should be able to download sectionals to your USB storage in the car, when you're on WiFi.  Then, map redraw, zoom in/out, pan, etc should all be almost instantaneous.  The only live data that would populate the stored maps would be the road congestion, supercharger status, etc.

In my opinion, this is a candidate for critical update, and a big safety concern.

Please, please, please put this on the short list for future (next?) update.
another use is when travelling in remote areas where LTE/3G isn't readily available.  I drove thru the GW Natl Forest a week or so ago.  The GPS worked fine and kept the routing correct.  But the maps were just greybox placeholders waiting for a data connection.


Google maps on your phone already has a way to download an area in advance.  Would be nice to be able to do this in advance of driving in non covered areas.

Or, even better, if the car/network knows you're heading into that kind of area, cache some in advance.
