how to edit nav600/900 theme files and start up animation.

[Doraemon02]

So a couple of questions guys:

I've updated to v208 my navi system last friday and everything went well.

However, today I've received a sdcard with the recent maps of europe 2015/2016 that I bought, and when I inserted the card in the system it told me that I had to install the version that came with it... Wich I think it's a lower version than v208!

I've already installed it because with it the sd card wouldn't work.

So now my questions are:

- Can I update to v208 again or the system will only ask me to install the version that came with the card again?

- When I updated to v208, the night sky became all orange and grey instead of the night sky with the stars (which I prefer), is this from the 208 version or from the theme that I've chosen? Can it be changed to the stars sky?

Thanks!
