Hi All;

I have a Garmin Nuvi 1690 with latest firmware

I need 2010.01 Turkey map and downloaded the IMG Unlocked at post number 2 supplied by catymag

I put the unlocked img to F:\.system drive of Garmin (main drive where preload map located) as gmapsupp.img

But the device can not recognized it , In settings menu under maps section I can only see preload map: CN Europe NT 2011.10 and tgicked, no other maps

Any other suggestions please ? How can install this map to my nuvi 1690

Regards
