2008 EX35 - GPS lagging

Postby sherwooa » Tue Aug 27, 2019 11:43 am

Anyone else experience very slow response from the GPS/Nav? I know it's an old system and we pretty much always use Waze for route guidance these days, but the map is sometimes helpful to have open while driving around to see next street, intersection, etc. But recently the GPS positioning on the map has been very laggy and incorrect, and puts the car in the wrong spot on the map.
I've run a self diagnostic and there are no communication errors with the GPS antenna (or anything else), and I've tried viewing the "GPS Satellite Info" in the Info menu item and I do see at least 2-3 satellites most of the time, so not sure if this is a GPS antenna issue or not.

Any ideas or experiences with this?

Hey Sherwooa,

The navigation in the EX35 is based not only upon the GPS, but speed and position sensors within the car. Did you modify your system by installing a brake override or some other mod?

I know this because when I installed the brake override I disconnected the signals in the wiring bundle and had the exact symptoms you mention. When I reconnected the signals the nav worked fine.

If you think this might be the issue, I can review the wiring diagram to try to figure out which pins carry the signals, just let me know.

I have same issue, it works just fine, and suddenly it is going out of its mind. Shoving car in wrong spot and sometimes tracking to wrong direction.
Keep in mind I own 2017

Hi pilotbob. Thanks for the reply and sorry for the delay in responding.

I haven't done any mods to the car, so unless there is a problem with a speed sensor then there shouldn't be any reason for that to be impacting the GPS system. It's possible a prior owner did, but I don't have any reason to believe they did as I don't see a brake override, etc.

did you ever figure out what was causing it?
