DIY: MAJOR MOD: NAV hacks / Entertainment System

Has anyone else tried this?

I'm having a bit of trouble with WileETundra's pulse circuit.

In the schematic, he indicates that nothing is connected to the wiper of the potentiometer. That doesn't make sense to me electrically, and if you look at the photos of his boards, it appears that pin 8 etc. is indeed connected to the wiper of the pot.

Has anyone actually built one and can comment on this? Or, WileE, is there a schematic change?

I can't believe I had to go back and look at the app notes for a 555, but it's been an awfully long time since I've worked with analog electronics. For those who are interested, pin 8 (and it's associated connections) should definately be connected to the WIPER of the potentiometer.

In my case, I'll pull the pot, rotate it 90 degrees (I'll have to extend the legs a bit) and replace the IC and hope for the best.

Despite the little diagram confusion, thanks still be to WileETundra for figuring out the timing and pulse arrangement in the truck.

I decided to just write each mod up in full detail and post on a website which is easy to navigate without sorting through all the threads and posts. As part of this I do have a bunch of photos of my NAV mods described in this thread. I am still working to put the final finishing touches on the NAV install to make it super-perfect but here are a few pics as a teaser to hold you over...

And before anyone gets upitty... no I am not going to stop posting on this forum. My personal Tundra website is just to house the high-res photos and keep copies of the relevant mod info organized all in one place. It will feature lots of links back to this forum which I think is the best place for questions, sharing, tips, discussions, debates, etc. My website is just going to be a few simple content pages, no ads, no contact info, and the only links will come back to this forum.
