I am not sure which one fits my desire.
Probably convert.
The idea is that I have a brand new running 3790T and after I saw what improvement has sg/mal firmware I am tempted to convert my Nuvi to this firmware.
But really I do not want to have a "brand new" unusable Nuvi, so before I act, I need to know all about this topic.
May be o good advice will help me and would be much appreciated.
