Tried searching for an existing thread, but didn't have any luck, please redirect if there is one. On top of the GPS directions not being great (i.e. it picks "scenic routes") I frequently notice that the actual location shown on the map is totally off even after I have been driving for sometime. For example, was driving in downtown Seattle the other day and it showed me driving in one of the lakes instead of on a road. I have also noticed that frequently it loses the direction that the car is pointing (i.e. I am driving North and it suddenly thinks I am going West) and re-routes based on that inaccurate information (this happens most often when I am stopped at a light). These issues make the GPS/Navigation close to unuseable on the car as it is constantly re-routing me. Anyone else have this problem or know if the new map update available also fixes GPS triangulation? Looking forward to iOS12 so I can just use Google Maps/Waze .
We're you driving around tall buildings? GPS can lose signals in some conditions. Also GPS signals can bounce off buildings and really show confused results.
Mine did that exact came thing once or twice. Once was after exiting my garage and the satellite icon blinked, indicating, I assume, it was searching for a satellite fix. The location was off track for a few minutes. I later reset the head unit and installed the update. It has not done it since. I have no idea if either of those things fixed it or if it just stopped if it’s own accord. It hasn’t done it again in over 3 months. In my garage the satellite icon blinks which I assume means it’s searching and can’t get reception. Now as soon as I pull out into the open, it stops blinking and very quickly works normally. Besides the satellite icon at top of display to the left of the battery indicator for your Bluetooth paired device, there are a set of strength bars that appear on left side of the screen when you select Map and then Back. Mine are yellow and 3 bars and then turn green with all the bars very soon after leaving my garage. Again I assume they indicate the precision of the location fix. Can’t find any info in the manual about these two indicators. You might check and see if you’re getting a good satellite fix when this happens to you again. I’m always amazed that GPS works as well as it does considering that the signal from the satellites is about one millionth the power of the local FM station. With that said, the GPS antenna is located in the dashboard and the reception can be understandably affected by items like a dash cam, radar unit, or phone holder placed there. The manual says metallic window tint will affect the signal but my ceramic tinted windshield is not causing any problems. Hope this helps.
Thanks Ken, I will look at the signal strength to see if it gives me any insights. I don't have tint nor anything else that would be blocking it. I don't think it is caused by buildings as I have seen the issue when I am in fairly wide open spaces. Frustrating that my phone is always accurate, but the car is so unreliable.
I can't remember offhand if there is a way to calibrate the compass in the Clarity, but if there is, try that. Maybe it isn't set for your area.
I had some issues while driving in downtown Boston a few weeks ago - the GPS would lose what road I was travelling on and recalculate the route .... I assume it was due to the big buildings that surrounded me at the time - I've had similar issues with other GPS units in the past (both portable and in-dash units). Other than that it has worked fine for me in general.
If my phone's taught me anything, you will need to do donuts and 8 to recalibrate the campass.... Let's hope you don't need to do the roll and barrel too...
I briefly looked in settings and couldn't find anything. In prior "dumb" vehicles such as my Pilot, I needed to program the area (i.e. Western US) we were in for the compass that shows direction in the rear view window to work correctly, but my assumption is that this "smart" vehicle should be able to calibrate itself as the GPS should be able to tell the system what locale I am in.
I've been driving through buildings, in the Santa Ana River, though parks, several street over, going the wrong direction, recalculating over and over etc. My navigation tells me I'm just everywhere, except where I really am.
Don’t know id this will help since I’ve never had to try it, but you might try a head unit reset. Just hold down the audio “button” until you get the message asking if you want to reset. Also, the GPS antenna is in the dash, and manual says not to place anything on top of dash tha might obstruct signal. Let us know if it helps.
