Yes. See: http://www.prolech.net/contact_us.asp?id=7&.html I've gotten great responses from Shirley & Coco. Maybe, and yes. I haven't found a way into the recovery menu (but I haven't looked either). However, Prolech did send me new firmware (named "MT-5001 software update accuracy 3", datestamp 10 Feb 2017) that's supposed to improve the GPS receiver accuracy & time to get a position fix. I've reflashed my unit to that firmware several times after messing it up. :) I'd ask Prolech for the latest firmware -- and please let us all know what version you get! If Prolech won't send you an update, contact me privately.
