I thought the latest firmware was 6.2, do you have inside information from Garmin?
Apologies - my mistake. Serves me right for using my Ipad instead of waiting til I got to my PC. I realised that I had made an error not long after I posted it, but by then the edit option had disappeared. I didn't do very well with this post, did I ?? !
6.20 is indeed the current version of the firmware.
No, I don't have anything to do with Garmin.
