@@smnkm4ehfer Since Gallardo is a spanish word I prefer to use the ll spanish sound to keep the correct original pronunciation

Thanks!!!!

You need to grab the CruisingGeekCommon and put it in your arduino library folder which on windows is under documents\Arduino\libraries\ github.com/CruisingGeek/CruisingGeekCommon

@@user-yi1gr3li4d The rotary encoder plugs with 4 wires into the Arduino. The arduino plugs into the swc input of your head unit

There’s a wiring diagram on my github page linked in the video description

Voth Productions does the best work! Was happy to have them spend time with the car.

If you don't have the SWC input with the mini stereo connector and only have the key wire you need a decoder unit that converts the buttons to the appropriate format the head unit understands. Something like this: www.crutchfield.com/S-SlSN48NP9BM/p_794ADSMSW/iDatalink-Maestro-SW-Steering-Wheel-Control-Adapter.html?XVINQ=GZ0&XVVer=Q0Q&awcr=628587969356&awdv=c&awnw=g&awug=9033300&awkw=pla-296046287922&awmt=&awat=pla&gad_source=1&gclid=Cj0KCQjw7ZO0BhDYARIsAFttkCjVZrQtiRYW00SxzZ-GFWYP-L6I8ipBLz502qx6Dm5-v5N7L04oWjsaAmMHEALw_wcB The arduino would then communicate with the Maestro, and the Maestro would hook to your head unit.

You would be surprised at how old/crappy the eRNS and HVAC stuff are in these cars. Lambo put all development costs for the 2009 MY year into the new 5.2L v10 so still same crappy stereo from the early 2000s Audis

You're welcome!

Thanks for your response. Even if I agreed the bigger screen helps so much with reversing that it was a must install since I daily the car and need to see when backing out

Absolutely. Pm me or send mail to [email protected] and if you’re in the area we could make it happen

All the libraries I used are CruisingGeek common, which is also on my github account

github.com/CruisingGeek/CruisingGeekCommon

Make sure to download this library and put it in your arduino library folder when compiling your project and it should compile correctly.

Good to know! Thank you very much for the help!

Honestly I would say not 100% necessary especially if you use the Motul low particle oil (xclean i think they call it). I haven’t accumulated much since running the system meaning it’s not creating too much blow by under normal driving

But I recommend for peace of mind as my Audi TTs was super dirty after 100000 miles

Agree, I love my local independent.

I generally don't check the email associated with this account and didn't see it in my main email. Could you try again to [email protected], that's the one I actually check regularly. Thanks!

That's awesome! You are going to love your Gallardo, it has classic lines and is beautiful from every angle. For upgrades, the best I've made are the PS4S tires and the KLA shift paddles. The latter are getting really hard to find, so hope you can get a set. This catch can kit would be a 3rd as it is a great peace of mind but be warned it did start leaking... video coming by next week explaining that and the fix.

Thanks so much! They really enjoyed the car a few years, and just traded it in to land a really nice SUV and they could not be more happy.

Glad I could help! One note - make sure your Pioneer is one that has the audio-style mini jack for the SWC control and editable buttons built-in. Some of them just have a single wire and require an external device to decode the buttons, which works but in my opinion complicates things more.

@@cruisinggeek3640 Yap, you are right. I'm now working on my own head unit, and yes adding a arduino makes it much easier and cleaner. Did you think about using Rpi and LineageOS to make own head unit? I have now a problem that the build of the latest LineageOS for Pi (made by KonstKang) doesn't realy support GPIO programming because android ... and I have no idea how to shut it down safely without touching the screen every time before I get out of the car. And yes, unfortunatly gpio-shutdown doesn't work if added in the config file...

Are you asking which MOSFETs to use? I listed the exact ones I used and bigger/cheaper alternatives in the video description. If you are asking what is a MOSFET, it is basically a switching circuit that allows a low power/voltage circuit (arduino) to switch an external circuit that sucks more power/voltage than can be handled by the arduino.

Well neither. The Gallardo being designed for the 2004 model year is way behind in terms of tech. For the LP/2009 refresh all development went into the new drivetrain and the electronics that run the car are still old school. This is the first car I've owned in over 10 years that doesn't even have auto headlights, you HAVE to turn on the switch when it gets dark LOL (there are daytime running lights that are always on). So yeah, I HAD to use the mic provided by the ATOTO, though I generally don't talk while I'm driving, I'd rather hear my v10 than anyone's voice even my wife, and that's saying a lot LOL.

That exact one I used might not be there but there are tons of 3-packs of pro micro clones www.amazon.com/Hosyond-ATmega32U4-Development-Micro-Controller-Compatible/dp/B09C5H78BP/ref=sr_1_3?crid=2Y8WAL13NOKBU&keywords=arduino+pro+micro&qid=1698372198&sprefix=arduino+pro+micro%2Caps%2C141&sr=8-3

The 360 does mean it spins infinitely. I do not know of a rotary encoder that has more than just the left and right infinite spin and single press button integrated

Ok thank you, also what about the fact that my head unit has only one steering wheel function wire? It is a blue/yellow wire that is part of the wiring harness. The wiring harness I am talking about is the one that has all my power/ground/remote/spkr wires/illumination etc. It is not like yours or some other stereos that have a seperate auxilary input for the SRC. I'm assuming it will still work as long as I use the blue/yellow wire as my power and the ground wire that is part of the wiring harness already. Do you know what I mean?

Yeah... if you have the one wire thing you will need an external mastreo unit to decode the SWC and send to your head unit: www.amazon.com/Maestro-ADS-MSW-Universal-Steering-Interface/dp/B00J4W10XG/ref=asc_df_B00J4W10XG/?tag=hyprod-20&linkCode=df0&hvadid=312765622753&hvpos=&hvnetw=g&hvrand=5761320742676852570&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9033300&hvtargid=pla-634754805597&psc=1&mcid=8b004dbd6aa53121aab047d4d9e05c4e&gclid=CjwKCAiA7t6sBhAiEiwAsaieYu-xlK8byy-DeBCZuDSZvgJRWvcTe3pu_BYtehTFSAXKEHYLUcd6ABoCfSUQAvD_BwE

Sweet, good luck with your search!

Resistors are just the standard off the shelf 1/8watt through hole ones. I have a stash of them here and just grabbed a couple that were far enough apart and over 1000ohm so that the head unit could differentiate them. Values don't matter too much as long as they are far enough apart that the computer can tell the difference (like don't use a 1,000ohm and then a 1033ohm one). Either an N-channel MOSFET or NPN transistor is needed to switch the higher power draw of the head unit, otherwise you'd be pulling that power straight through the CPU which either won't work or could damage it. I have plently of those small MOSFET boards here from a previous project if you need to buy a couple, though you said you had a pretty tight time crunch.

@@cruisinggeek3640 would you consider making one and selling it ?

@@blastros10 I'm dealing with some health issues currently so not really in a position to do that right now but definitely something I'd consider in the future.

Right now the arduino is used to interface the SWC (steering wheel control) so it does not utilize can bus. You would need to update the programming for outputing the appropriate can bus signal via the PWM pins on the microcontroller and hook that with your radio. Note that most aftermarket head units have SWC though so this method should work, though if you are trying to do a custom volume knob with a factory unit you would probably need the can bus implementation.

You need to download the common library from my share and put that in your arduino libraries folder. github.com/CruisingGeek/CruisingGeekCommon

Audi won't work on Lamborghini's in my area at least since there is a Lamborghini dealership in the area. I've found an independent though Veloce motorsports with Josh who used to work at Lamborghini and he's the best in terms of the work and prices so that that's what I've been doing since this.

@@cruisinggeek3640 That's weird considering they're under the same umbrella.

Believe it or not I'm dealing with what I believe right now is a very small valve cover gasket leak. When I use the car for a long time it starts smoking near the rear-driver side. I do see some very small hints of wetness around the gasket, so thinking they need to be replaced. This happens as a car this old that wasn't driven much at first tends to have premature failure of the soft bits.

I agree!!!!

What MOSFET did you use?

Really glad it helped! I was surprised when I made this video that no one had done it yet as a volume knob is like the most critical function for the radio.
