Hi everyone, what do the 4 figit code after the map version indicate? For example, West Europe v890.4222 versus West Europe v890.4234? The maps are the same until a new version (say v895 or whatever) comes out correct? Or do the numbers show the functionality (4222 has speech, not sure what 4234 offers above 4222)? Thanks for any help & answers.
In the next version v895 maps, these numbers will be totally different and are chosen by TomTom.
