After replacing that img. file to SD card it becomes "invisible" to the nuvi. At the same time a "new data" files (poi for example) were easily recognised with suggestion to place them into internal memory. A little later SD card "falled off" So, to my mind I have a hardware problem and the solution is- dump!
If you use garmin.com services you will recieve message that map is already updated in any case if the map is not from City Naviagator series. Download new version of Road of Russia from here or download any old version and then use mapupdater from garmin.ru. By the way if you do not have garmindevice.xml in device it is halting of protected internal memory probably and you have lost official unlock too.

What's name of img file do you use for SD after copying? Only gmapsupp.img and gmapsup1.img (SW ver.6.20) are available.
