Hi, two problems with my igo 8 chinese sat nav device:

1. The help button on the sat nav shows an error message, is there a way to fix this?

2. It gives weird directions sometimes. For example on google maps if i select bicycle for a 20 mile route, it will intelligently direct me away from dangerous roads. On igo 8 no matter what method i choose (bicycle and fastest route, shortest distance, economical etc) it always directs me on the dangerous roads (they are single lane but high speed 60mph).
Is this just the limitations of igo or can it be fixed?
