how do u open a garmin nuvi 660 to replace speaker?

remove 2x spline head screws on the antenna, separate the two parts, then there is slot on the left hand side bottom hinge section,slide this back with a fine screwdriver which in turn retracts the left hand hinge be careful it is spring loaded the spring is inside a plastic cover both will come out once the antenna is removed. now remove 2x splined screws situated behind the antenna head, now the 660 splits in half from the sides and top first, just be firm with a fine blade,the bottom has location tags,and pulls away once the top/sides are pulled away. remove 2x cross head screws on the inside board, gently separate the inside boards, the speaker is then on a push 2x wire connector and is stuck onto the back of the 660 with tape, as far as i could read the specs for the speaker are 8ohm 1watt. just be gentle with the separating. good luck
