Hi, I would advise not to erase any of the Garmin supplied files. If your device can use a sd card, that would be the best place for Garmin suitable osm maps. Here is a detailed guide that is likely to be suitable for your gps and should get you up and running
https://www.dcrainmaker.com/2019/08/how-to-install-free-maps-on-your-garmin-edge.html
Here are osm maps for download
https://wiki.openstreetmap.org/wiki/OSM_Map_On_Garmin/Download
Note that the site described by dcrainmaker and provided by Lambertus is not operational and that is unlikely to change, so you will need to use another provider. Currently the predefined country maps may be ok I think but are out of date (June 2020).
The procedure to install the maps is similar on all the sites but they have different web site detail, and there is help available on all the sites I think.
I have found the bbbike site maps work fine for me and updates the osm data about weekly.
https://extract.bbbike.org/
Most of the other map providers sites are equally suitable.

Hi Thank you for the help it didn't work. Somehow the sd card is not being read by the garmin nuvi 860t. I have tried it on 2 new sd cards after sometime it even doesn't show up on the computer unless you eject and reinsert it. to add to this now while trying to reformat the sd card , by mistake formatted the garmin device. it now doesn't show anything at all. is there any possibility to restore it with the baseman and then just install the os map ?

Mmmm..... formatting the Garmin drive was unfortunate...probably best to give Garmin a call about that.
Sd card does need specific format... fat32?
The Garmin Nuvi 860t is from a few years ago and the file name may need to be gmapsupp.img You could put your .img file on a thumb drive in a garmin folder and then use Basecamp to transfer the file to the sd card on your gps. If Basecamp reads it ok it should be fine for your gps.

You may be able to reset the gps or update it though I expect a format stifles that. You will need to choose the map in ‘changing the map settings’ and the ‘map info’ setting.
