Sprint GPS problem

[mommasboy]

I did a search and couldn't find anything that really answered my question. I have the $30 vision pack and I'm having a problem with my Telenav. It keeps aking me for my credit card info. I called sprint and they verified to me that I have Free Gps, but they told me I needed to download there GPS. I told them I already had telenav and they told me it was the wrong one. They told me to look online and it said i need to go to my web browser type in "nav" and then follow the rest of the instructions. I tried this, but it keeps coming with an error. Is there really 2 different sprint GPS programs or is sprint giving me the run around. Thanks to anybody that can help me.
