empty can of some kind..
Jewelers Flat Blade Screw Driver
Jewelers Phillips Head Screw Driver
**basic soldering skills**
remove Nav unit from car. (if you struggle with this, then stops here DO NOT go further)
there are 4 screws on each side and 2 on the top and bottom of the face plate, remove these and pull off the Knobs
(volume, tuning, Joystick)
(thank you Jaak for providing these pictures)
use small screw driver to top pop the tabs that hold the face plate on.
Remove the PCB board:
4 screws hold it in place:
remove the connector on the left side
place the unit on a mouse pad or some other type of anti-static pad.
I personally use an empty tissue box, because I can set the unit on it with the knobs inside the opening to prevent
damage to them.
Desolder the old joystick, make sure you EMPTY the desolder iron after each pass (empty into the can) or you could
spit hot solder onto the pcb board and Bye Bye Navi Unit.
this is a desoldering iron $25 at Radio Shack:
look at the difference in the 2 joysticks.. if the new one (shorter shaft) bugs you then you can do the following and
swap out the shaft:
A. dissemble the old joystick:
use the flat blade screw driver to lift these four tabs:
remove the shaft:
repeat the steps for the new joystick and swap the shafts.
Now resolder the new stick in place:
If I recall there are 15 points to solder, the stick only goes in one way so you can't mess that up,, but BE CAREFUL
not to bend the ends as you insert it, they break kinda easy.
YOU DO THIS AT YOUR OWN RISK.. DON'T BLAME ME IF YOU SCREW UP YOUR UNIT
