I want to install Rotweiler's All Thailand Routable Version 3.0 on a Garmin Nuwi 200w.

I already have Thailand Street Maps latest version in the machine.

I understand I will need to buy a memory card and I was thinking of installing the Rotweiler on that memory card.

Is there an option in MapSource to install the new map to memory card instead of direct into the Garmin device?

What size of memory card do i want to purchase? (the size of the downloadable map is 91.2 MB )

Thanks in advance!

Will be following this closely as I am looking at a 200w or a 250w from Europe. Both are 120 ish GBP so 7k ish baht.

I assumed simply adding a memory card would be easy.. At thier current prices just buying a larger one than required makes sense to have places I might go added (HK / Bali / Etc)..

Be very careful. Any map you install with Map Source will delete the map already on the card. I would strongly suggest you buy more memory cards and use them for any other maps you want to use. Any map you install goes on the memory card. The internal memory on both of mine stores tracks, waypoints, routes, etc and no maps.

Also for some reason my 128 MB memory card won't allow me to install a 95 MB map. Says not enough memory. One GIG cards are not that expensive so that's what I bought. If I buy more cards, I would buy several 256 MB cards. and a 2 GIG for the US map.

You can install however many maps you have room for with Rotweiler's maps but don't try to put another map on with ESRI because it will delete the ESRI map.
