StreetPilot c3x0 and c5x0 are somewhat similar in appearance but differ radically in operation. SP c3x0 are 'region-only' devices with no visible file system exactly like the earlier StreetPilots and GPSMAP devices. SP c5x0 on the other hand are more closely related to nuvi 3x0/6x0 range and they do have a visible files system accessible in Mass Storage Mode like all modern Garmin devices.

I think that you won't be given the install to SD option by GarminExpress with such an old unit. All you need do is click on 'Map Options' on this screen:

[Only registered and activated users can see links. ]

Then you see this:

[Only registered and activated users can see links. ]

As you can see, even with such an old map as the last official update i'm offered a reinstall. You can also download the PC Version [gmap folder] to your computer and make your own custom map to fit on the unit or an SD card using MapInstall.

If you want the latest available UK/EU maps free go here: [Only registered and activated users can see links. ]. Keep in mind that you'll be unable to use a single map for the whole of EU in one *.img file because your unit can only see a file size of less than 2GiB. You could make 2 files if you need all EU, one for the unit's Garmin folder and one for SD's Garmin folder [named only gmapsupp.img] keeping both under 2GiB.
