Garmin Nuvi 200w Motherboard Replacement

Einleitung

The motherboard on the Garmin Nuvi 200W is a circuit board in the device that operates the whole device. The motherboard occasionally has a component fail, preventing the device from working. Should this happen, the entire Nuvi 200W unit will be inoperable.

This repair is best done in a clean, dust-free environment. The sensitive electronics inside the Nuvi 200W will not respond will to sand and other small particles. It is also important to leave yourself ample time to effectively navigate the motherboard removal process.

Werkzeuge

Schritt 1

Peel off the sticker in order to find the two Torx T5 screws.

Schritt 3

Carefully, using your plastic opening tools find the crease which separates the front and rear covers.
Once you have a little gap, work it around the whole device with the tool to get separation.
There is a ribbon cable between the two covers, be very careful when taking them apart to not damage the ribbon.

No connecting cable in the picture. Perhaps include a photo or direct the reader to one in a future step.

Schritt 4

After the case front and rear are separated, carefully lay the two sides down without disconnecting or damaging the orange ribbon cable.

Schritt 5

Carefully use the black spudger to lift the white retaining clamp on the display cable ZIF connector.
Make sure to lift up on the white retaining clamp and not the ZIF connector itself.
Slide the orange ribbon cable away from the ZIF connector.

My 200W had a different connector arrangement. I couldn’t disconnect the display cable which connected into the middle of the motherboard not the edge as shown, nor the other two cables either side, but if I was careful I could get enough clearance to undo the screws holding the motherboard (one of which was under a metal screen which was stuck down but could be peeled back).

Schritt 6

Using a screw driver, unscrew the four 2mm screws holding the motherboard in place.
Gently lift the motherboard away from the rear cover. Take care to not damage the wires or ports that link the motherboard to other components.
