Map not on SD card after instalation with R link explorer

I finally was able to install the map on the SD card.
I am not sure if this is the cure, but here is what I did.
R-Link and also my device was formating the card with 7 files (tomtom.000, etc) of 2 Gb each ( card is 16 Gb). I was trying to install a 4 Gb map on the card.
I redimensionned the tomtom.000 file to 5 Gb using R-Link and reinstalled the map on it.
To redimension, I had to use some of the accessory programs included with R-Link, following the instructions given by R-Link when trying to redimension.
Bingo!
