can you try with NTU 2013.10 ?
On my device Nuvi 3790 and Nuvi 1490T maps CN 2013.10 and CX 2012.40 work together
Same problem here. Nuvi 3490 with CityXplorer 2012.40 and CN2013.10 NTU. If i remove the CN 2013.10 NTU the CX shows in the list and work. With CN2013.10 instaled, CX is not visible in the map list and it allow only walk or drive (no public transport). The strange think is that when i try to switch to pedestrian mode - it's written Powered by CityXplorer.
Unfortunately my device have LTM and update going automaticaly to NTU verssion. Please advise how to cheat the f... map.
I guess cityxplorer for CNEurope 2013.1 is never going to appear !!
