How to Update Software on 2015 Excel Hybrid 1.5?

[Gaurav]

We just bought our first car - a used 2015 Yaris Hybrid Excel 1.5 CVT. So far it has been good to us but the multimedia interface could potentially be better. So I thought that maybe there are software updates in last ~2-3 years as this car must have been made in late 2014 or early 2015.

So I am trying to figure out how to update the software. I registered the car successfully on www.toyota.co.uk but am unable to add the Multimedia device there. The instructions for registering talk about 3 different types:

Toyota Touch & Go

Toyota Touch 2 With Go Generation 1

Toyota Touch 2 with Go - Generation 2

 

I did try to register as first option of Toyota Touch & Go but the device ID doesn't match. System Information for my vehicle is:

 

Software Version: XE3864

Model ID: 13TXDAEU-CA02

 

I don't see any device ID. Then I tried with Go Generation and paired my Android phone via bluetooth. But I don't see any option of "Connectivity" or ability to setup a Personal Hotspot on my phone to share with the car. My screen options are:

 

General

Display

Audio

bluetooth

Phone

Vehicle

 

Does anybody have an idea how to:

1. Register the Multimedia Device on Toyota Website?

2. Or perhaps more importantly just update the multimedia console of the Yaris?

 

Thanks a lot for any tips or pointers. Best regards!

You probably have the Touch 2 with Go first generation.

As far as I'm aware the second generation came out in 2016.

audio software XE3864 > a Touch 2 unit. if you also have "with Go" (nav) there is certainly an update & iirc it is free (there will then be further, chargeable mapping updates available). http://blog.toyota.co.uk/toyota-touch2-with-go-receives-major-software-upgrade

I don't think that there is an equivalent update if you have Touch 2 only without Go but Devon Aygo should be able to confirm.

A 2015 Yaris will have Touch 2 but the fact your device ID has no mention of the navigation version and that there are no settings for mobile hot spot suggests you do not have the "GO" navigation module installed, what happens when you press the Nav button on the headunit?

In terms of the the head unit there is a software update XE3943 which includes bug fixes this can only be completed at a dealer and does not alter the user interface at all,

Thanks for your very informative and helpful replies. We do not have navigation. If I press the Nav (arrow) button on the headunit then it just tells me that I don't have navigation. Thus, I presume that our car doesn't have "Go" (nav) feature.

So then it appears that the best bet for us is to take it to Toyota dealer for an update. We can't do anything ourselves, correct?

Happy New Year to all and thanks again for your replies.
