When driving with Carplay active and displaying Google Maps (no route in progress), I have a 'weird' situation. The map is displayed with the direction on the top (not north on top). Situation: Occasionally the display will slightly spin either clockwise or counterclockwise and then immediately spin back to normal. Almost like the GPS lost its mind for a moment.

Thoughts?

Thanks for any insight.

 

Running a similar setup (phone, software, etc) and have this happen frequently. Just returned from a business trip and the same thing happened in the rental BMW. It's annoying when i catch the "spin" out of the corner of my eye, but I don't think it's anything to be worried about.

 

Thanks for confirming that at least I'm not alone.

 

I have noticed the GPS screen doing a slight twist or spin around a bit when we go thru one or two particular spots in our area. One is wide open so no overhead obstructions, but the other is under a tree canopy on a mountain road. I've not tried zooming out to see if that stops it as the spin is just for a second or two at the most.

 

Apple doesn't appreciate you using google maps. They would rather you use their POS map app with the nice 3d buildings and make you miss turns. I'm obviously a Android user... Rest of my family are iPhone junkies. Although iPhone documentation states that the built in AI is suppose to determent which music or map app is used the most and uses that information to set your defaults for you because they think you are too stupid to set them yourself, I've had to program short cuts and try all kinds of tricks to get google maps to just show up on carplay on boot. At one point Apple literally stopped my shortcuts from working without user intervention. I don't think I've ever had google maps do a spin on Android Auto that I can think of... maybe 180's but no 360's. Carplay has maps doing 360's almost daily. Sometimes when the shortcuts I programmed kick off google maps just has a black screen and we have to click the maps icon to get the map background to show. Apple would have to come out with something supper crazy to get me to buy a iPhone... Like a AI assistant that can predict the market and never give me a losing trade.

 

I can't speak for Carplay, but on Android Auto the map orientation is configurable. See the attached photo. Tapping the compass indicator on the map lets me choose between North upward (my preference) or direction-of-travel upward. Again on AA the setting is sticky across vehicle starts.

 

CarPlay is the same and works perfectly for me.

 

Did you ever think rather than the GPS signal going astray that it is the 4-5 G signal that is momentarily lost?

 

Certainly had not thought of that, however, what would that have to do with it? I don't think the GPS does anyyhing with the cell service other than map data.

 

I assure you does when precise location setting is enabled . I work with gps daily and we connect to cell towers with our equipment to triangulate the signal. It gives us GPS accuracy down to 10th of a foot if conditions are good.

 

1/10th of a foot. Surely not for vehicle tracking using map data. Maybe it's for tracking drones.

 

I'm still thinking it is a Carplay issue. I have never experienced this with just Google Maps in my other vehicle without Carplay.

 

If a map service used both GPS and streamed data for better accuracy they would run their own stationary GPS (base station) on known coordinates. Since its stationary and the coordinates are known it can make real time corrections and pass that data on to other devices. It would most likely bring an error of 50-100ft down to 10-20ft depending on how far these base stations were away from the device receiving the corrections.
