I just purchased a Drive 60LMT to replace my Nuvi 1450. Before I say I regret it, perhaps someone has an answer to these questions as Garmin is being very mum on their "support" requests.\n\nThe first problem is that it instantly filled up it's memory to 100%, and now will not take any more updates, say it's full and to contact support. Support suggested a SIM card, and "Josh" said as soon as I do the next update and the Garmin sees the card it will immediately start using it and solve the problem. Three cards later (thinking I had the wrong cards), still nothing, and the Garmin won't update. According to the docs I could go as high as a 64gb card, but I put in a 32 since I don't need a ton of storage. Windows sees the Garmin (Full) and the External card (Empty), but it still won't update.\n\nGarmin Express "help" files don't yield anything of value, and so far Garmin has not responded. Is there a trick to getting the 60LMT to recognize the card, or is it just bad and needs to be returned/refunded?
