One doesn't need too at all.Originally Posted by principecarlo
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.

Update on the crashing 3590. I cleared the nonvol as suggested and though the unit worked faultlessly on a one hour drive i decided to check the unit indoors. I turned the GPS off and sat and scrolled the main europe map. After about 10 minutes it started slowing right down on the map loads eventually crashing the unit.
Initial thoughts would be an issue with pulling the map off the SD Card. However I'm pretty certain the SD card is fine. I've checked it in a Card reader, reformatted, etc and it gives fast data transfers and shows no writing or reading issues. Also the fact the card will work from the outset without issue would indicate the card itself is probably OK but maybe it's a problem with the Garmin unit accessing the card through whatever interface it uses.
I will put the Europe map on the Garmin - it should just fit and try this but it's not a complete solution as I like to use the Michelin guides in basecamp and they only work if installed on the Nuvi (and when they are there in not enough room for the NTU Europe.
Neil mentioned removing all other maps which I'll try, I notice that I've got gmapbmap.img on the Nuvi 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.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.
Gmapdem.img is DEM data map for your CN detailed map

They work on the Nuvi but not in BaseCamp. Or at least that was the case when they were last only on the SD card.
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. Originally Posted by cloud

I'll try removing the guide but I'm not so sure it's the culprit as the guide had worked fine for a long time prior to the crashes. i wonder if i were to post a screenshot of the files on the Nuvi drive and the Sd drive someone could see if there are any old files or files that shouldn't be there?
