How big of microSD memory in terms of Giga Bytes can the Garmin Montana 650t support? 4GB, 8GB, 16GB, or 32 GB?

I'm using a Sandisk 32GB microSD card in my Montana 650t.

I was told it over-heats?

No, mine never has had a heat problem. I have used it both in the winter cold down to -10 degrees and in the summer heat up to +98 degrees and have had no problems. I store and carry mine in a leather pouch but have it exposed to the air while using it.

does this allready have blue charts or do you need to purchase the chip separately ?

You have to purchase it separately.
