I want to know what your plans will be if you are having problems with Telenav 5.1 on your Pearl. I don't know all the reasons so I am guessing at some of the options, if you don't see the option close to what you will do please create a post in this thread to note what you plan to do. Here are the options:

1. Cancel service so you don't waist any money while waiting for them to fix
2. Wait and pray that Telenav fixes the problem (1 month before cancelling)
3. Wait and pray that Telenav fixes the problem (3 months before cancelling)
4. Wait indefinitely and pray that Telenav fixes the problem
5. Research other options and cancel service when you find one
6. Downgrade OS if you are on 4.2.1.x to see if that fixes the problem
7. Purchase a Telenav GPS puck to see if that fixes the problem
8. Do nothing

If you're having problems with TeleNav 5.1 and your "unsupported" BT puck please post your results in the following thread. If we can get good feedback to TN maybe we can get a fix.
