Just purchased the 66i and went to Garmin Express to download all the updates. There were over 30 updates listed and an estimated 3 hr for the download. My plan was to do them 1 at a time rather than accept all. I download the first update which was maps and installed on the 66i. Went back to download the other updates but Garmin Express says that my system us up to date and I’m running software version 6.3. Am I fully up to date with everything or is there something else I should do?
