Are there other choices for the N810 GPS than the build in software?

Think I would like to do:
1. Trace a path while doing bike or other outdoor activities and save the file to upload to a mapping software (google earth) or only capture the GPS data, save it to a file and upload to PC.

2. The map build in are very old. I am in Quebec, Canada and my street where I live is 20 years old and not there.

3. Is there some library that I could use to build a software myself?

Thanks for any pointers

Simon
