a nuvi 205w supports two maps in internal memory---garmin directory---gmapprom.img and gmapsupp.img
and only one map on the garmin directory of your sd card---gmapsupp.img

you can merge many maps using gmaptool.exe ---maximum combind map size of 4gb---

thanks vincent for ur such quick reply
but right now the problem is that i dont i have installed the gmaptool but it is not running if u have any link from where i can download kindly send it to me
