I just tried loading some to my new Garmin 450 also. I use a PC and it tells me I must be a premium member...which I am and was already logged in. I cannot get them to send to the unit...don't have old ones to erase, and honestly....it's super annoying. I'm not that good with the different file types and what they mean etc. I feel like I should be able to follow the instructions and have it work like it says it will. LOL...age and technology...ugh! If anyone has idea's I'm open to hearing it. Thank you.
