My understanding from Garmin is that there are major improvements, including sensitivity, accuracy and bug fixes. I would like to update the unit’s firmware from the currently installed V2.60 (October 2003 Bravo 7) to the last available from Garmin’s website V.5.20 (March 2008). Sending downloaded pocket queries from my Mac to my Venture works perfectly.
The Venture screen shows the unit is charging (electric plug icon). I am using a Garmin 4 pin to USB all-in-one cable with a Prolific PL2303 driver to connect the Venture to my Mac. Has anyone in recent times successfully updated the firmware on an old green Garmin eTrex Venture to the most recent V5.2.0? If you have, how did you do it?
