Garmin nuvi 2445LT

Hi all, great to have found this.
I have a question about an older Garmin nuvi 2445 LT, 4GB internal memory.
I found out it doesn’t have a micro SDslot so I have to deal with only the internal memory.
I did a search here on the 2445LT but nothing came up.
It is possible to use the OSM maps for the Netherlands on this device and if so, where do I put them.
Although I have removed a lot of unnecessary files(all foreign voicefiles) it still has only 400mb of free memory.

I hope someone can help me out.

Thanks in advance

Im not familiar with all those nuvi models but maps are often stored in a folder called map or garmin.
Netherlands will not fit on your device so the easiest thing to do is to install the map on your computer with basecamp and send the tiles that you really need to your Garmin. Please note that there is a bug in the latest Basecamp/ Mapinstall version, read also the sticky topics.
