extracting with rar 5.31 to device sd card,
I use a Tomtom go 720.
Despite your problems, I'm afraid that Central_and_Eastern_Europe_965_7250 is the previous release map and also it doesn't have any meta code released so you won't be able to activate it.
Being as you're using an SD card and I'm assuming NC 9.510, you could go for Europe_970_7466 which is the latest series and does have meta available.
