I too experienced the Toggle (Joystick) failure. I removed the Navigation unit and opened the display housing. On the inside bezel of the display I found 2 small circuit boards. I removed the small circuit board containing the joystick and found that all 6 solder connections were fractured due to the fact that the mounting bracket tabs that go through the circuit board were never soldered. The joystick is a surface mount device, and by not soldering the mounting tabs on the other side of the circuit board, will allow the solder joints to flex and eventually fail. Even though all 6 solder connections had fractured, I was still able to move left, down and select. Even though this is a surface mount device, the connections were easy to re-solder. After re-soldering the connections turn the board over and solder the mounting tabs. After the repair, the joystick worked great, more responsive than ever!
Although this was not difficult to repair, it will require a great deal of care and a good mechanical aptitude, I can not stress this enough!
Removing the bezel from the navigation display was not that difficult, however when replacing it DO NOT SNAP IT IN UNTIL YOU GET THE CLOSE BUTTON [non-permissible content removed] POSITIONED AGAINST THE FRONT OF THE CLOSE SWITCH, or you will shear the plastic close switch actuator off of the switch causing permanent damage!!! I know this first hand. Fortunately I found a replacement at Mouser, Part# 101-TS4722R2200-EV. The dimensions are exactly the same and it looks exactly like the original switch. The only difference is that the new switch doesn’t have the two alignment bosses on the bottom, so You will have to position it manually.
In my previous post I used a word that is used to describe a part of a woman's anatomy. Unfortunately it resulted with the following:
"DO NOT SNAP IT IN UNTIL YOU GET THE CLOSE BUTTON [non-permissible content removed] POSITIONED AGAINST THE FRONT OF THE CLOSE SWITCH"
So I have revised it as follows:
DO NOT SNAP IT IN UNTIL YOU GET THE CLOSE BUTTON BUMP POSITIONED AGAINST THE FRONT OF THE CLOSE SWITCH
I like my original version better!
Yea, those words with multiple meanings can be tricky
More important, thanks for the info about the fix! Always great to hear about DIY fixes. Good job!
Here is a pdf with photos detailing the repair.
Always nice to have a step by step with pictures! And THANKS for not making that into a loooooong post and tucking it into a pdf
