Navigation system keeps losing me! (1 Viewer)

[drgordon13]

Not sure if anyone else has had this problem on their LC or other Toyota...my navigation map will lose me...Let me explain:
I have gone through recalibrating the navigation to where the map is all correct...I will drive for a day or so and all will be going fine...I will then not pay attention and when I look at it again the navigation will have lost me...the red arrow is moving but it will be no where near my actual location...I can recalibrate again and it just continues happening...anyone else had this happen? any fixes? Thanks

How are you recalibrating the navigation?

I go into System>Navigation>Detailed Navi. Settings>Calibration>Position/Direction...I do it from my house so I know exactly where I am and my position...like I said it functions properly for a while. For instance, I had to do it yesterday and it followed me just fine to my mother's house about 5 miles away and back.

Do you have an aftermarket carplay/AA interface? Have you ever tinkered with the radio/screen, i.e. removed from its location to look in the back?

YES!!! It happened to me once, lasted about 2 hours, then corrected. I posted in this thread where others were posting about various GPS issues:

It might not be relevant in your case, but typically when I have a glitch in anything electrical, I establish a high impedance air gap for a reset. In other words, I disconnect the battery or unplug the power for a couple minutes.
