Thank you very much for your patience, #catymag, with webupdater it worked out easily, but...

Only with the file you sent me in that link (nuvi2xx7and2xx8_530.gcd - HWID 2077).

All the other files from Perry, from 4.70 and 4.60 back to nuvi2xx7_GCDFile__270.gcd, did not work... And the version 5.30 still does not allow for the installation of other maps in my nüvi 2597. From my investigation, I really need minimum version 4.60, but the one I got from Perry does not work.


So, could you check if there's, perhaps in the archives, other option for version 4.60 HWID 2077?
