[Jeff Clymer] owns a Ford Focus, and while he’s generally happy with the car, the “My Ford Touch/Sync” system can be buggy at times. He spends a lot of time in the car each day, so when the entertainment center locks up as it is frequently known to do, he has to turn off the car and pull a fuse to reset the system. Since pulling a fuse while on the road is pretty impractical, he decided to install a reset button, making system reboots a breeze.
He started by disassembling various fuses until he found one with an easy to remove fusible link. Once it was in pieces, he soldered a pair of wires to the fuse terminals and connected everything to a normally closed momentary pushbutton switch. After adding an inline fuse holder and reinserting the original fuse, he installed the button into the back of his glove box
Now instead of physically removing the fuse each time his stereo locks up, he can simply push a button and be on his way. Here’s hoping a software fix is coming for [Jeff’s] car sooner rather than later!
