Interesting, that is indeed a very unique cable. Any part number on yours? My cables all say Garmin on one side, China on the other.Let me reconfirm that by using this one Garmin USB cable on my Nuvi 1340T it completed the update and I no longer have this problem with Garmin Express telling me there is an update.
Mine have lifetime map updates, it's a 1490LMT, not 1490T as I mistakenly wrote, so I still have map updates for it.This series Nuvi's are old and do not get any updates any more
Well, it has been over a year already, but, I will try to be more patient, hopefully the update will install by itself, eventually, one day. I just wish I knew how to trigger the GPS to install the update.In my experience you just have to be patient
Thank you all for your time.
