Purchased City Navigator Europe NTU (2013) on a SD card for my Zumo 390LM last year. Basecamp can read this SD card with street detail sufficient to find addresses and points of interest. But when in use in the Zumo on the road in Portugal this winter, while the audio instructions are spot on, the screen display would not zoom in to nearly the same level of street detail provided by my internal North America map when in use back home in Canada. No amount of fiddling with the Zumo settings seems to fix this. Has anyone else experienced this issue? Garmin Support no longer supports the 390LM so will not offer any advice but I suspect this problem is probably common to other Garmin Zumo units.
