Hello & Welcome to Just Answer,
To better answer your questions, may I ask:
1) Is this an "LM" model (with Lifetime Map updates)?2) The AGE of the device?3) Is the device still in good condition (works with the current maps)?
We experts are users of the site - just like you - and have no access to any of your private information including any CC information.
But you should have an "Account" link on your page, where managing any aspect of your account can be done.
Please let me know if you would like to continue with your questions about your device. I'm here almost every day to help.
Take Care, Greg A.
