Your PNA210T has been sold in 2006, 15 years ago, and there exists a Flash ROM to upgrade this device to R19 ROM. This ROM R19 allows you to run Gopal 3.x versions.
Since there are neither GoPal 3.x versions nor any GoPal 3.x maps available by this board, there is no sense in upddating such an old device. Even in case you own these programms and map data by yourself, such data would by very much outdated.
I would rather recommend, you buy a
Medion Navi device such as the P4440 or P5260, which can be obtained by eBay for small amounts. Such devices can run the latest GoPal 6.x or 7.x with maps of 2020. You should consider,
Medion quit the support of maps in 2020 and there will be no updates in the future.
Sorry, but this is the situation.
