Yes, I installed the full map (unlocked MapSource through Basecamp) to SD and copied the 2 ASR files to .System/ASR on the internal memory.

I just tried using the unlocked .img and that doesn't work either.

Are there different ASR files for different devices? When searching for help I found another thread for a different map set with different files for "ASR'2' files for 3490/2495/2595/359x & other ASR capable 2012 & 2013 devices + SID files" and "ASR'1' files for 3790/2460". Do I need a different ASR file to the one posted?
