Hello fellow members. I'm really new to this and it's abit overwhelming. I bought a head unit on marketplace and it didn't come with a gps card. My question is for a beginner, how would one make up a gps card for this type of unit? I'm from Australia. Also whenever I try to change the time after a minute or so it reverts back to 2001.
