Well, in my case as in many others it was luck and it worked without the dealership.

Take a look at the survey here: Toyota Touch & Go 2 - MM17 Retrofit Update inkl. AC & AA

Is there a dealer in your area who can help you? Then spend your money there. The german dealers I heard from replaced the device with a new one (guarantee) or resettet it with the help of Toyota Europe in Brussels, Belgium. But until now I did not hear of a simple fix for that problem.

If you prefer to buy a new device, I would recommend to buy a MM19. This is already with CP/AA ex factory and you don´t need to risk another upgrade attempt. And I think it should not be much more expensive than a MM17 as a used device. (In case you can send yours back...)

The dealer in my area know nothing about . I tryied to search the new MM19 on ebay and I find nothing. I don't know the new parts number, the results came out are the old moudules, such as 86140-02730.

See my first sentence above.

You can try it (if you´re interested in european maps in your car). Maybe you will have success, maybe not... There is no guarantee. By the way: "Touch 2" is nothing else as "MM17" and "MM19". One is the selling name, the others are the internal names.

Sometimes the upgrade fails because of damaged files on the USB-drive as a result of copying errors. So you could try to download the files again to your harddisc, then copy them again on an empty flashdrive and try again. Unlikely but possible.

I don't think the problem it the USB3 damage files,I tried it servral times,It stucked at line 69 with red error.Because there are a lot people met the red retrofit error 001. But the refoit successfully at the dealer's shop.

missrolan: "Touch and go" means with navigation. So you will get not only the DCU device but additionally the MEU module. I think you don´t need that, as it´s got only european maps.

For the european Corolla there are two different head-units (both Panasonic). The 2019 model was delivered with MM17, which does NOT support carplay or android auto. Since 2020 model it´s got the MM19 WITH carplay and android auto.

If your ebay device does not have CP/AA, it´s the MM17. Its model-ID is something like 17TDT1EU-DA01 (01 or 02 at the end, not 31 or 30).

This device can be upgraded to MM19 with the files on USB 3 (drives 1 and 2 are only for the versions with navigation / MEU). But in some cases as in yours the upgrade fails. In this case only the dealership could help be resetting the device to delivery status.

So maybe it could be an option to send it to Toyota Motors Europe or a dealer here. I don´t know if that is a useful hint for an ebay-customer in asia.

But if you like buying new head-units this could be interesting for you:

Dasaita head-unit: https://www.amazon.de/dp/B08D3FLB84 (Unsere Seite enthält Affiliate-Links, für die unser Forum möglicherweise eine Vergütung bekommt.)

Some users of this board already have it in use as you can see here: Alternative Head Units

Or an android extension of the existing head-unit could do it: https://carperformance.se/prod…9-up-android-extension-2/

The easiest way should be to buy a MM19. But also the most expensive I think.

My unit was MM17.And I update it fails with USB 3.So I'm thinking if I got a Touch and go, maybe I can updated it successsfully.

So if I buy a toyota touch and go 2 back,and put it on the car . Can I update the DCU system successfully?

okay, das klingt logisch (ging für mich nur nicht ganz eindeutig draus hervor). Dann muss er das Problem aber auch "lokal" lösen.

Kann ich ein Upgrade erfolgreich durchführen, wenn ich einen Toyota TOUCH AND GO2 zurückkaufe?
