Is there a better config than TT V7.910 SW on a MIO device with WIN CE V5.0 available?

I have for some 5 years TT software V 7.910 (Dutch) with Windows CE V 5.0 (2004) on a MIO device (M315 and S305 with SD card). GPS control progr. v1.20.
RAM 35,7 MB.
ROM (flash) 1,79 GB. + SD card.

It works great, but time sync does not work automatically in winter/summer change and after reset. I have to remark the Sync time box every time.

Is there a newer version of WIN CE and/or the TT app. that should work on MIO M/S 300/400/500 devices? And solve this problem? Or is there another solution?

Or is this the wrong thread to ask this question?

Thanks in advance!

There is no newer version of wince and also not of the TT app.
The best solution is to use Igo Primo or Igo 8
