Navigation Update Adventures
I purchased the Garmin map update for my 2011 Jeep RHB. Installation was rather interesting. Upon inserting the DVD, a unit ID and validation code are displayed. One must then enter the info on the Garmin web site and receive a unlock code that is then put into the RHB.
You are then told that the update could take up to 2 hours. I think that the actual update took about an hour and 15 minutes. The problem was that if the accessory switch was left on, but unattended, it timed out in about 30 minutes. If that happened, the update starts over. So I trotted out to the Jeep every 20 minutes to recycle the accessory switch.
Once updated, the map settings were changed, so one must go through them and restore the settings.
After all the effort, the update looks good.
