957 INSTALLATION MANUAL, Revision C1
Returning a 957 
system for service
The 957 is covered by a two-year hardware-only warranty, 
which, in summary, states that if the unit is returned to the 
factory by the owner or dealer during the warranty period, 
Northstar will repair or replace, free of charge, any part found 
to be defective due to faulty materials or workmanship if the 
system has been properly installed and hasn’t been abused. See 
the Limited Warranty Policy at the front of this manual for 
further details. The only cost to the owner will be the one-way 
shipping charges and any associated charges that may be 
imposed by the dealer. If you have overnight or second-day 
shipping requirements, before shipping the unit, please call the 
factory for turnaround time, freight charges, and payment 
arrangements. 
The 957 should be shipped only in a properly designed carton 
with packing material, and to the Northstar factory at the 
following address:
Northstar Technologies
Service Department
30 Sudbury Road
Acton, MA 01720 USA
Maintaining the 
957
Basic maintenance
At the end of the day, wipe the 957 off with a damp cloth. 
Cover it with the sunshield to protect it from excessive heat.
CAUTION!
You may want to back-up any user-defined waypoints and
routes before returning the 957 for repair. See the Northstar
957 Operator’s Manual for details. 
Before returning the 
957 to the Northstar 
factory, to prevent 
delays, it is critical that 
you first obtain a 
Return Materials 
Authorization (RMA) 
number from the 
Northstar Service 
Department. If the 957 
was purchased 
through a dealer, call 
the dealer with the 957 
serial number so they 
can help you get an 
RMA number. The 
957’s serial number is 
on the label at the 
back of the unit. 
Shipments without a 
proper RMA number 
will not be accepted!
