Hello, Fellows!

I have bought Garmin nuvi 2450LM with North America maps. I live in Russia and sometimes I need to travel to North America. So my problem is that I can't see cityXplorer maps. I have CN North America 2013.10 in the internal memory, on the 16GB microSD card I have CN Russia 2013.10 and CN Europe 2013.10. North America maps are legal, Russia and Europe are from torrents and came unlocked. All these CN maps are working smoothly in the drive mode. I want to load cityXplorer. I took 10 digit ESN number from my device, generated unlock code for FID800 (no PID2, other options by default) then I put CXNA 2013.10.img + CXNA 2013.10.unl in the "Map" folder on the memory card. Go to simulation, set position somewhere in Montreal and try to see EPM - no luck.
1. I renamed files to gmasup3.* - no luck
2. I put them in the internal memory \.System - no luck
3. Put to the "Garmin" dir on the memory card - no luck.
4. Tried to generate unlock code for my CNNA 2013.10 maps (FID:2360 PID:2) - no luck

According to specs 2450 supports EPM, but may be I use the wrong method to unlock? I use small maps and tried JM keygen 1.5 with checksum fixed and 5 digit keygen - result is the same. What do I do wrong?

Thanks in advance, any help will be highly appreciated!
