If you're in the market to buy one at auction with DMR enabled, always make sure the seller can supply a picture of the screen stating "DMR/MOTOTRBO has already been activated..." Don't just take their word for it (same applies for the other paid upgrades). If you end up buying the radio you'll also want to ask the seller to provide you their activation key in the event you need to send the radio out for repairs, you'll be able to get the upgrade reactivated
