So, I'm doing the mod to get back my dvd and nav functions (N1) when moving and as Murphy would have it, it went terribly wrong. I have done plenty of soldering and had the right equiptment for the job. I soldered down the first end of the wire and went to solder the second to the point by the row of resistors, and when I did it, it seemed a little loose so I gave it a quick melt to make sure it was secure. The wire popped up off the board and I noticed there was no solder on the board. Solder will not adhere to the spot and I don't see any copper trace there. I know I didn't overheat it, so I can only assume there was a board issue of some kind. I need schematics and help to figure out where (to and from) I'm going to have to jumper to repair this damage. My degree in electronics is decades old and not used much, so I need help from those of you who are better practiced. I took a picture for what it's worth. Thanks, Ski

I need a much clearer picture of what was below that wire you tacked on and maybe a pic of a guide you used to do the mod then I can help you. In the mean time from your description it sounds like you took the top layer off of a via (makes connections between board layers) since it is a multi layer board you may have destroyed the whole board but that is unlikely. If there is still a hole there you can use a 30ga etc wire and feed it though the hole, solder it on the bottom and attach your mod wire to the top.
