UPDATE! PROBLEM SOLVED! Prius C - my GPS keeps getting lost!

View attachment 61353 View attachment 61353 I'm looking for others who have had this problem. I've got a 2013 Prius C 3.

I've attached two photos and what I did was do directions back to where I actually was. One photo shows me 2.7km (well driving distance not as the crow flies) from my actual location - the other was 9.3km away from my actual location. I've tried stopping and restarting the car. It is not consistent but when it happens it is like that for the entire day - it is between 100m to >30km (yup - last week it said I was 32km away from my house in a lake which has no road access!)

This has been an on and off issue since I got the car in November. There is no definite place that seems to cause the loss of GPS. I had a Venza and Highlander with GPS that never had this kind of extreme problem. I live in Metro Vancouver - not like satellite coverage is poor. There is nothing that could be obstructing the antenna (that I know of).

Has someone else had this problem and how was it resolved? My dealership has been talking to Toyota about it to replace part of the GPS system but even with my google-ing this doesn't seem to be a major problem with other Prius C folk.

 

Thank you Zephr7.
I'm in Canada - no Entune. My dealership isn't sure. They haven't had anyone else have this problem this extreme!

Today I'm around 5km out. And I've driven down the middle of the Fraser River today.

My Prius has a Chitty Chitty Bang Bang complex!

 

Maybe its because I have an old blackberry?

 

I've used GPS for 12 years.

From remote Yukon to Northwest Territories, Quebec, Nunavut and Amchitka Island, AK(google it-VERY remote!). I've used installed GPS in vehicles in BC and WA since 2010. Also used a very, very accurate GPS station in AK.

Never - ever - have I had one out by 40km even if the datum was set wrongly!

Toyota has decided to replace the head unit after checking software and so on. Will post when I know if that is the problem

UPDATE
my dealership finally ordered a brand new GPS unit from Toyota.

I've never been lost since.

So they replaced the GPS unit head and the new one worked well....

Until about a month ago when the "chitty chitty bang bang" syndrome started again then stopped. Two days ago it started getting really bad again. This time it is worse.... the GPS can't even figure out what direction the car is facing.

Emailed the dealership.... they said it might need the latest update... hmmm.... it was in for a service 8 days ago and somehow they forgot to do the update? ugh....

Anyway... we shall see what they decide to do. I just don't understand why my C GPS gets so lost and so VERY lost (up to 160km lost) and jumps around the place so badly.
