Hi again,

so i have used my garmin with my austria topo 2 (on a 4gb micro sd) for some time now (with my new bike - gives a lot of motivation) and it works very well. What I tried now is to put the city navigator europe on the same sd card, after using the unlocker for the img file. I renamed the file to gmapsup2.img (more than 2gb). Unfortunately, my edge does not show the map. I now that there is a thread how to put mor maps ....but it seems that most of the things described there is for the nüvi. FOr the edge 705 i have the following questions:
1: Should it work renaming the img file as mentioned above? As i am using the fast unlocker, i do not have an .unl file. I guess the process is different than for using jetmouse.
2: How many different maps can i put on the sd card on my edge and what should be the names for those (i want to use the fast unlocker as fooling around with mapsource seems to be more time consuming) and how many on the internal drive (and what names)? Is this the same as for the nuvi and are the names the same?
3: Do i need the basemap on the internal drive of my garmin or can i delete it (i do not think that my garmin uses this map) and can I rename another map of my choice as basemap (e.g., the city navigator or topo austria)?
4: Woud it be wise (and possible at all) to use the EZGmap or gmap tool to merge some maps into e one new map - and how big can that be for my edge 705? More than 2gb?

I went through the how to install multiple ....thread but for my simple mind, i came to the conclusion that there must be some difference between the nuvi and the edge, that is why i am asking those (for you) simple and maybe stupid questions.

Thank you very much for your effort
