Looks like you managed to correct the date on the nav system. Have you got it to say hello to you when you turn it on?
No, I haven't fixed the date, but learning how to put gpx points on a map made me wonder if there's an android app that store/save gps points as a similar gpx file and I found one on google play in which a review told me everything I wanted to know. I installed that and did did tests on it at work this week before taking on today's ride. Here's what the Honda one looks like:
Every time I turn off/on the bike it creates a new file and I have save them individually, then post them to a map one by one which is time consuming (and the date's wrong), but it does show points I stopped. Mind you, the android app allows me to add anecdotes which I did at Langhorne Creek saying lunch.
It says Hello Bodo when I turn it on. I changed that on my first ride. The only language installed is British English so there's no option for an Ø.
I actually videoed that sign on and sign off today, but as yet have not looked at any footage. I'm still in the process of copying files to my computer.
