ATTENTION: This is only for investigations and study propose, please if you like wayfinder, buy it.
When you open wayfinder, you can get a trial of 7 days, after that you have to buy it.
How can we get a "eternal trial"? easy, when this 7 days finished (really it's not necessary to wait, you can renew at 5 (for ex.) days left), follow these steps:
Remember $ means run as user, and # means run as root ($ sudo gainroot).
1 - $ rm -Rf /home/user/.navicore ( for me, this don't delete any map or any POI)
2 - Install macchanger (OS2007 version have to work fine) (this it's only necesary the first time, if you don't have macchanger yet)
3 - Go to Offline mode
4 - # macchanger -r wlan0
5 - Connect to Internet
6- Open wayfinder and get a new 7 days trial
Possibly i will made a script for to this, but is so easy, it's not?
Please comment your results, at least it work for me.
