My mother just bought a Toyota Yaris with a TomTom built in, it has application version 7.825 & Map 835.2421 (over a year old on a brand new car!).

Anyway, I want to update the map, but according to the chart on the 865 map thread NO maps work with this version of application.

I tried updating through HOME but the only updates were to mapshare/QuickGPS Fix, no application. I put the UK & ROI 865.3246 map on, patched it and the device using FastActivate, but it still said it could not use the map.

So the question is what map (& application if required) should I use?

Thanks.

Just a little more info, the device (according to TomTom's serial number checker) is an "Eclipse II / Toyota TNS410 / Toyota Aygo Connect Multimedia 2Gb".

The original map is Western Europe 835.2421.
The Application is 7.825
The Boot loader is 8.0032

Thought that might help!

Make a backup, patch the file ttsystem and then install the map for NavCore 8010
