I tried to update to v5.42, using my desktop pc and after update unit said complete.
After repowering machine, my unit still showed v2.6 EU, and no vehicle selection available.
After contacting support, they reminded me to update again. Still same result.
I finally decided to us my laptop pc. All went well, update showed completed the same as the other pc.
This time. I viewed tool information. It showed v5.42 GL, and I have vehicle selections now.
I can only assume the only part of the update loaded, causing my unit to still show old version, and no vehicle selection. I now have a market selection under the settings menu.
I hope this helps someone having any issues with the update.
