NUVI 760 - not reading Map on SD card

I am currently downloading 'Europe 2011.32' unlocked.

I have already have 2011.10b unlocked (gmapsupp.img) on my hdd. Although I've had this for awhile and this Garmin device is my sons, he is reluctant to remove his current onboard maps etc 'Garmin City Nav Europe NT 2008', but is willing to try a SD card with the latest Map of wherever.

I have a 4G SD card with the Volume Label named as 'Garmin 2011' and the img file of 1.95mb pasted.

I have renamed the img files with various names as suggested in various posts, but the device does not read the img on the SD card.

I assume the img file being unlocked, I donot need to do anymore than what I've done above.

Please advise where I'm going wrong and about installing the lastest Speed Cams onto the SD card alongside the img as and when updates appear.

thanks

put your map to SD-Card \Garmin\GMAPSUPP.IMG

HERE is Speedcam update and help

thanks,

I take it the Speedcam file is also loaded into the Garmin folder alongside the img file on the SD card.

thanks again

Speedcams go Internal memory \Garmin\POI directory
