12.4 My Account
In the upper-right-hand corner of the Extras menu, choose Account to view a list
of your subscriptions, your purchase history, and any payment information you
have on file. You can add a credit card to your file for quick payment from within
the Telenav GPS Navigator application.
12.4.1 Adding a Credit Card
Certain purchases, like movie tickets, are billed to your credit card. To add your
credit card information, do the following:
1. Go
to
Extras
>> My Account >> Add Credit Card.
2. Choose a PIN if you have not already done so.
3. Input current credit card information and choose Save.
12.4.1.1 PIN Protection for Your Credit Card Information
For security reasons, all your credit card information is encrypted and protected by
a 4 to 6 digit PIN that you choose the first time you enter a credit card number. You
can reset your PIN at any time, but doing this will clear all the credit card
information saved on your device (this does not affect your subscriptions).
NOTE:
If you input the incorrect PIN ten times in a row, then all saved credit card
information will be automatically deleted.
