Combining maps


Hello everyone, i have been lurking in the shadows learning a lot about my new Nuvi 255.

I have two questions. First of all is it possible replace the roads on one map with those of another.

for example I would like to replace the roads on my topo maps with the ones from city navigator.

My second question is regarding the speed at which my Nuvi zooms in and out. It seems that it zooms out at around 90Kph and zooms back in when going slower. Is there a way to change the speed at which this takes place?


You cannot replace maps/sections of maps/built-in POIs/etc with those of another type from another map.

Autozoom is a fixed algorithm and cannot be user-adjusted in any way, although on a couple of higher-end nuvis like the nuvi 5000 & nuvi 8xx, it can be disabled.

nuvi 760, nuvi 765T, nuvi 855, nuvi 3790LMT, nuvi 3490LMT - SoCal area
