Welcome to Justanswer.com, my name is Dustin.I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.
Whats the model number of your Garmin?
Also, do you have a mac or a pc?
Also, have you already purchased the oiltrax update? If so, from where? Thank you for your reply,
It wou ld probably be best if I connected to your mac or PC from here, and helped you directly on screen, to install the needed updates.
Ive sent that offer, and once accepted we can arrange a time to connect and speak over the phone.
