I put the code in the following link:

This is the new location where maps.xml can be found on my phone:
/mnt/extSdCard/Android/data/de.esymetric.rungps/files/Run.GPS
Backup original maps.xml and replace its code with the code from pastebin.
I removed services I dont use and I added Google Hybrid, Google Maps, IGN Sat and IGN Vector. National Geographic Institute of Spain -IGN- is really, really great to spanish users but it hasn't got maps outside of that country.
I got Google Maps working, yupiee!! It would be nice if they were added by default so all users could enjoy them.
Paste the following code in a file called maps.xml (backup the original first) and upload it to Run.GPS root folder inside your mobile (example: "/storage/sdcard0/Run.GPS")
