This troubleshooting guide assumes that you have
read and understood this manual.
It is possible in many cases to solve difficulties
without having to send the unit back to the
manufacturer for repair. Please follow this
troubleshooting section before contacting the
nearest NAVMAN dealer.
There are no user serviceable parts. Specialized
methods and testing equipment are required to
ensure that the unit is reassembled correctly and is
waterproof. Repairs to the unit must only be carried
out by a service centre approved by Navman NZ
Limited. Users who service the unit themselves will
void the warranty.
