Hi, first time posting and hoping someone can give me an answer. I unknowingly bought an older garmin gps map 546s that no longer is supported by garmin as it it over 15 years old, I wasn’t aware and am new to these kind of units. After searching all over I’ve yet to find an answer to my problem. The gentleman I bought it from I suspect knew it was outdated. It did work briefly when he showed it to me and when I got at home, it worked for about a minute next time I powered it up says transfer failed and I cannot get past that screen, I will include a screenshot below, any ideas on how I can solve this issue?
