A:Answer It will work in the Rexin Dashcam first of all. You can get all the way up to a 256Gb in most and I would suspect the Rexing as well, however, you are really just creating more video or footage than you will probably ever need. Normally when you have an event, you off load it somewhere safe or post it....Then if i have the card out already, I go ahead and format it to clear the footage I don't care about. Also, all the ones I have seen have auto-looping so that when the card fills up it just loops back and overwrites the oldest file.
So, get bigger if you care about all of the video footage, otherwise I used this size in all 3 of my vehicles.
