I have fitted a mobile phone holder to my Warrior 165.
Phones now are Cameras, Video cameras, GPS, Phone, etc. etc.
Unfortunately the holder pushes the side buttons and pulls the battery flat very quickly.
I recently bought a 4in one Lighter socket to use to charge the phone.
I sat for 1/2 hour, positioning and scratching my head.
I think I found the perfect spot.
This may be of use to others.
