With this bootloader (5.0500) 2gb SD is the limit
If you want to use larger SDHC cards, you need at least a bootloader 5.5022

how can I upgrade the bootloader? I started with GPS !

You can use any size SDHC card that you wish, by upping the bootloader to 5.5012 or higher.
Here is a link to Bootloader 5.5128. [Please Register or Login to download file] Unzip it and copy the "system" file, as is, to your 1GB SD card. Disconnect and reboot. Done
Now you can use your new 4GB SDHC card.

thx you for help ! works perfecly with 8Go SDHC, new navcore and new maps
