Ok so finally having enough of trying to find the board I need I decided to take it into my own hands and fix the radio myself. The mod I did will no longer allow use of the Timer Function or the Steering Rate Function, but I never use either so no biggie. It also seems to work nicer ergonomically this way, but that is my opinion. Plus no more busting cheap roller wheels. So here goes. Make sure before starting you have the Steering Rate turned all the way to 100% since afterwards it will not be adjustable.
After you have your radio in half you are gonna want to unplug 3 plugs from the main board. The Steering Rate Assembly,Timer Button Assembly and Roller Wheel Assembly.
Now you will want to snip the plugs off of the Steering Rate Assembly and the Timer Button Assembly. Take the Steering Rate Assembly wires and solder them to the Roller Wheel Assembly on the back side where the 4 wires are soldered on. White=White, Grey=Black and Purple=Brown.
Now take the Brown and Black wires of the Timer Button Assembly and solder them onto the board where the Menu Button is soldered in. I don't believe it matters which side is which color as long as one is on one side and the other on the other side. If you look at the picture of the back of the Menu button you can see 2 posts are "+" and 2 are "-" connected by the chip board. I soldered black towards the side that says "Menu" and the brown to the opposite side.
This is what it should look like when everything is connected up.
Now just install the Steering Rate Assembly, Timer Assembly and Roller Wheel Assembly back in the radio being sure to keep all wires out of the way of the internal moving components.
This is what it should look like noting that now the Timer Button Assembly and Steering Rate Assembly plugs are no longer plugged into the Main Board.
Now when the radio is powered on your Timer button will be your Menu button, and the Steering Rate Knob will be your Menu Selection Knob. Everything will work just the same as before except you won't have steering rate adjustments or a timer.
