The common problem of all encrypted map developer (like Ukrainian or Romanian) is using of not original Garmin SW. By another word the developer needs to re-rebuild (c..r..a..c..k!!!) original SW for each new version from official Garmin. May be it is very difficult for it or even it needs in participate of third party which is not free of charge!
The Garmin dealer for Romania is not right. Garmin company supports an older model like your. The City Navigator NT version is bright example for this. The Nuvi 200 works fine with the whole coverage map from mentioned version. All your problem is connected with Romania ROAD only. But it is your problem only because the developer of the map does not want to upgrade your device to prevent of using the other maps?!
I strongly recommend to ask the developer of Romania ROAD for SW update. If he do not answer with positive result you have full right to use a legal pressure because you have the very significant legal reasons for update of SW. The experience of Ukrainian users gives a positive result, sometimes In any case than more claims is the higher probability to force him to move...
