I have the Nuvi 40, I put the new map and jcv on the sd card. The new map is working fine but the device can not show any junction view as the internal 2012.1 map (49 states only) before. I tried both the D3191040A.JCV and D3060050A.JCV files one at a time, the results are the same - no junction view shown. The junction view file is in the x:/GARMIN/JCV directory. Any idea what is the issue?
