Ok I know this would definitely void any warranty on a PMP but I would like to use a different button to control the on/off status of the PMP but keep the dip switches and connections where they are. The previous owner of my car had some aftermarket electronic device installed which they removed before I bought the car. I don't know if it was a radar detector of some sort. All I know is there is a button installed in one of the blank spaces next to the factory buttons on the dash. It looks pretty clean and it also has a little light which would be cool to also reuse. The button doesn't do anything and it's actually not wired to anything anymore. It would be nice to be able to turn the PMP on/off via this switch. I currently use it to turn on the imaginary Auto Pilot but I'm willing to trade that functionality to be used for the PMP. I already removed the PMP from its case for moment to see what the inside looks like (well, there goes the warranty!) and it's just a simple little PCB. I have not successfully ever soldered something before. But this doesn't look impossible. I may just need to find the right type of soldering tools, the right switch if this one won't work for the PMP, and some courage. Whenever I tried soldering before I got frustrated at how small soldering joints are and that my cheap soldering iron tip may be too big. Another concern I have is finding the right type of solder to use for this and the right cables to connect the PCB to the new button. The button switch that I want to use says 16A 12V and has 3 "legs". I'm no electronics engineer. This is really the first thread I've created so hopefully you all can see the attached pictures of the button that I'm talking about.
