Yet another edit add due to "experiment". The CX full (NA) file will not work with my Nuvi 1300 unless I have an unlock "key"/file in there. Doesn't matter whether it's the A'dam key or one freshly made for the CX full (NA). I had read the entire thread before I began posting and I did read all of post 8. There are a couple of what appear to be contradictions within this thread or I'm just too tired to make the distinctions. Too, I had the read the instructions on unlocking. I'm confused beyond a reasonable doubt at this time given post 27 is directing no unlock file is needed?
No, that's not what i said in Post #27:

I1136F74 NT 18818609 1 1252 30 L 1 2920 HOUSTON, TEXAS

You may have it loaded with any version of CNNT other than 2014.10 provided you don't have them both selected at the same time. Check only the one you're using at the time. That info is in post 21 immediately above your initial post here.
What i said there is clear i would think, I didn't say no unlock file is needed: The NT parts etc have the original FID and are unlocked. The MMR parts with FID 800 still need the *.unl file for EPM to function work [but the last part is left unsaid]. The user i was answering clearly understood that by his earlier posts, so there was not a need to restate it at the time.

As to why your Chicago map worked with an unlock file named differently i can't say. I haven't tried that, the convention has always been for the *img & *unl files to be named the same and I believe that to be the case. I'll try and report my results.

BTW, FIU is good, but slow. Better to use [Only registered and activated users can see links. ] or [Only registered and activated users can see links. ] for unlocking images.
