I have a nuvi 55 LMT and I have problems with the last map updates, with Garmin Express.
I have the problem, even I change the computer (PC or Mac) or I try the computer update, only.
I have these messages in the logs :

Normally, I have nüMaps Lifetime
Europe update, but it seems to have problem to activate the new map ... (Internal Server Error ?)
I reset the software (5.40) of the gps : same problem ...
I upgrade Express (4.1.25.0) : same problem ...
I try map update, on SD card, only : same problem ...
I think the problem depends of my gps datas on garmin database.
Is anybody knows this problem ?
Thanks.
