What happens if I have two different UK maps enabled on my Nuvi?
Background:
I have UK OpenStreetMaps and the standard Garmin UK maps. The Garmin maps are old and they want £75 for lifetime updates yet they do contain postcodes. The OpenStreetMaps are 100% up to date but do not contain postcodes. When both are enabled I get postcode searches but what will I get on the maps, say where the maps differ?
I cannot find the answer anywhere and it's very difficult to test.
Thanks
