Garmin periodically issues updates for the firmware that gives increased functions and fixes bugs.I already had wine installed because I needed it for work related compatibility and found it "just worked" for this process. The Nuvi will start with a black screen with "Garmin", a progress bar and a icon of a nuvi connected to a computer. I download the Webupdater, but it cannot connect to the Nuvi even though it recognizes it. I also have the same unit, I have no problems updating software and maps, but you do need to follow c764's advise for the system to work. I use it hiking, biking, boating and in my car and even use it as an MP3 player when bike riding.
Except for new nuvis that may be entitled to one free map update, Garmin requires either a numaps One Time map update (probably not worth the expense) or a numaps Lifetime purchase (about or so which will entitle you to up to four map updates per year for the life of the unit--you will need to decide if this is worth it. Due to a good combination of features, these units are better than most later nuvis, especially the inexpensive ones. Also, 5.30 was released a very long time after the model was discontinued.
Web Updater installs software updates on the nuvi 250 that may fix problems or improve the device's functionality. Connect the nuvi 250 to your computer via the supplied USB cable.
Allow the device to charge fully before proceeding with the update.
If you plan to take the nuvi 250 with you when you drive to your next business meeting, update your device's software before you travel.
Garmin provides the free Web Updater application for updating your GPS.
