Touch 2 with Go Plus keeps forgetting login credentials

So I have the Toyota Touch 2 with Go Plus on my Toyota Prius Excel (edit) here in the UK. In the Connectivity settings, you can connect your phone to it via BlueTooth or WiFi so it can download traffic information and speed camera locations.

But, if you also enter your Toyota Online login details in those settings, you can do stuff like configure a few car settings via the website, and also from your PC create Sat Nav waypoints/addresses, and routes, which all magically appear on our car when you get into it and it connects to your phone's internet connection. It all works great!

Apart from the fact that I have to keep re-entering my username and password in the Sat Nav for my Toyota Online account. Despite checking the box that says "Remember username and password", it seems that after some time (days, weeks?) the car forgets it.

What's weird is that I know it remembers the login for a short while. I just checked now, and after a couple of hours of the system being off and it still logs in fine, and you can see my username and a bunch of **********s for the password. But in the last 5 or 6 weeks of ownership I've had to re-enter the username and password three times now. When this happens, all of those details are blank, and the "Remember username and password" box is unchecked. It's doing this itself - nobody else uses the car.

Anyone else experience this? Any solutions / suggestions?

 

Especially if you use a secure password, like me. 20 random characters, upper and lower case, symbols, and numbers. Takes forever to enter. Time to change it to something easy like "abc123"

Oh it's an Excel. My bad. That's what having two insane infants keeping you awake all night does to you

You don't need to log in for those functions to work, they're tied to the Sat Nav automatically. You only need your Toyota login for transferring settings, waypoints, and routes that you create via a browser.
