None really, mine has packed up.
The charger port is susceptible to breaking off the mother board. Poor customer service, very poor quality control when it comes to repairs.
I used my Navma F20 only 10 times before a problem developed with the USB port and it would no longer charge from the car (a common problem with the F20). I sent it back for repair and it came back with the same fault, and now the unit is incapable of finding a satalite, despite having performed a factory re-set of the GPS. (hold down on/off button & menu button together to enter maintenance menu). It has now got to go back a second time for repair. Navman don't seem willing to replace it until they have had at least three or four goes at fixing it they tell me. Please review this unit carefully before you part with your money as it seems a lot of people are having problems with this satnav.
