Stein told me that the GTX 23 can be updated remotely, but I can't find any information about how to do it. Can this be done? If so, is it via a serial port or through the G3X (I have 370's)? Want to know if I should leave a pigtail with a DB-9. Garmin won't update them at Osh anymore.
Thanks for any guidance on this.
