Not using Andnav2 anymore

In my previous post I was explaining how to create map tiles for andnav2. But I have since stopped andnav2. The main problem being, I was kind of lost and wanted to use it and guess what, I get a message saying my version of andnav2 has expired and I must download a new version. Indeed when I am lost that is the perfect time for me to upgrade.
I am looking for alternatives, feel free to help me find a better one.
I tried navit but as of now still unable to get it to work on my G1.
