The circuit writer pen doesn't crack. Solder does. I learned aircraft spec soldering more than 30 years ago - I'm really good at it - but I also know what it does not do well. Solder should never be used on something that flexes (including wiring harnesses) because solder cracks, and because flux wicks up the joint and will corrode over time. This introduced invisible wiring failures which are a nightmare to troubleshoot (just ask anyone who worked on 60's and 70's era aircraft before soldered Cannon plugs were replaced by crimped pin Cannon plugs).

If you want you can ship it to me as long as you take it out of your car and pay for shipping to me and back.
Huge difference DO NOT USE SOLDERING IRON. I learned this the hard way.

None really other then take your time, and make sure you move your shift lever all the way down towards the back seat. I can't stress it enough. That and the ac vent removal is really the hardest part in my opinion.

I am going to give this a shot today. I have pulled hundreds of Lexus's apart so that is of no worry to me - it's just the whole circuit writer thing I am a little confused on. Do I expose the copper that's on the ribbon or the part that is on the glass? I don't want to do it and put it all back together and it not be right...
Thank you,
Jonny

I think Vroomin350 had to do things a little different. I think he exposed slightly under the glass and on the ribbon itself. I will PM him this thread so he can chime in here for you.

Jon, what I did was with an exacto knife and magnifying glass (that was built into my table with lever so I don't have to hold it) I exposed the 1 and 3 strips on the ribbon to reveal the copper underneathe them. For me it was 1 & 3 and I verified this with a multimeter... Once I exposed the copper I then began to "write" with the pen. It's very easy actually. You basically just scribble a couple of times with it. Then I waited about 15 minutes (though you don't have to) and when I came back I recheked with a multimeter that it was good. After that you're done put it all back together. (although to be safe I plugged up the nav without all the fancy exterior plastic and verified it work before applying the plastics.

I'm just pulling the NAV unit out as we speak

the trick to the pen is simple. once you expose connecttor "pin 1" simply get the pen and put some of the liquid to fill where the piece u cut out used to be. Its self explanatory once you see it really, however make sure u practice with the pen first before going at the screen, it can get tricky not putting too much.

It's not easy. The hardest part it scratching the glass off the reveal the copper. I tried it once and it didn't work. When I get a writer pen I'll try it again. I might need to etch away more glass.
