RT82 has two hardware version: GPS & Non GPS. If you radio is GPS version, you need to upgrade the GPS firmware. Otherwise, after you upgraded your radio will show white screen, snow screen, or other problems. So if you want to upgrade your RT82 firmware, make sure you choose the right firmware version first. After we know the GPS meaning, now let's learn what's the meaning CSV and REC.
RT82 supports to record function or import 100,000 contacts. but you only choose one, RT82 can't support them at the same time. That's why there are two different editions. If we think the contacts is important for us, we can upgrade the CSV firmware. If we think the record is important, we can upgrade the REC firmware.
