Thread: Nuvi 3590 keps crashing

Some more things to try and test in this order:

1. Clear nonvol [non-volatile memory]. It's a little more comprehensive than a hard reset: [Only registered and activated users can see links. ].
2. Replace the microSD with a known reliable or new one or move the EUU onto the unit if there's enough space.
3. Remove [not just uncheck, move off the unit/card] ALL other maps [detail maps, DEM, 3D Buildings] except your current EUU and basemap of course.
4. Replace the basemap: [Only registered and activated users can see links. ].
5. Redownload and replace the EUU map.

Basemap 5.01 is only 49MB (approx), yet 2.00 is 101MB (approx). Does one really need to replace a more detailed map with a less detailed one?

One doesn't need too at all. V2.00 predated V5.01 by almost 4 years [06.06.2007 vs. 14.03.2011], which is really of no great concern because highways change little in that time and DEM changes not at all [we'd hope anyway]. The presumption of less detail is reasonable on the surface because of the smaller file size, but rather than necessarily being less-detailed, V5.01 has been far more compressed by the mapmakers thus saving over 50 MiB of space on the unit. But most relevantly because all 3590 worldwide had V5.01 as OEM from the factory anyway afaik. V2.00 was OEM for much earlier units [2x5W for example]. Either can be used, but a more compressed map may make earlier units 'laggy' whereas later units such as 3590 can handle it because of enhanced processing capacity. Having said that, 3590 can use virtually any basemap including V2 WW DEM or an even earlier regional non-DEM one such as Atlantic from nuvi 2x0/3x0/6x0.

but also have gmapdem.img on the SD card a 317.8 MB file dated 10.01.2012. Should that be there? is it a worldwide basemap if so what is gmapbmap which I see is also referred to as a DEM?

Thanks.

gmapbmap.img is a basemap containing DEM data showing in the basemap only.
Gmapdem.img is DEM data map for your CN detailed map

I transferred them back to the Nuvi (which meant installing the NTU Europe on the SD Card rather than the Nuvi) and at that point they reappeared in BaseCamp. Unfortunately it was soon after that that my problems started with the Nuvi crashing!

Yes I realized it and removed that text from my post.
Have you tried to remove the guide, may be it causes crashes in nuvi, just an idea, because you wrote they happened after moving it to internal memory
