What GPS navigation software, without a monthly fee, can I get for my Palm Treo Pro?

My Palm Treo Pro (850) unlocked does not contain Sprint Navigation, Webraskar Navigation, Google Maps, or TeleNav programs. It only has QuickGPS, which doesn't show any map at all. I don't want to use TeleNav because it has a monthly subscription fee of US$10. Is there any GPS navigation program that I can install on the Palm Treo Pro running Windows Mobile 6.1, that does NOT have a monthly fee, and that uses actual satellite signals. I'm quite disappointed that I can't use the GPS right out of the box, and that I actually have to pay more in order to use the GPS hardware that I bought. The product was promoted as having built-in GPS / standalone / autonomous GPS as well as assisted GPS. I didn't know you actually have to pay more to get to use the built-in GPS hardware. I suspect that I would have to shell out more money for a GPS software to run on my Palm Treo Pro. I don't have a choice, I guess. What I'm hoping is that the software that I get is actually compatible with the built-in GPS receiver in the Palm Treo Pro.

Can I use Garmin or TomTom software with the Palm Treo Pro's built-in GPS receiver?
