A:Answer Hi! Pretty much any micro sd card should be fine. I always recommend a name brand with a capacity of at least 100 gig capacity or more.
You are correct that this camera does not come with a memory card however, it does come with its own download & power cable.
Using the Garmin App you will download to your smartphone, you should be able to delete un needed footage manually as well as save what you need. This works via Bluetooth.
Be aware - Once the memory card is full, the camera will begin to overwrite itself so, try to keep it cleared. If this is isn't a concern, just be sure to save what you need using the App, if you need to do so. Enjoy!
