I have a 20/20 gx460 and when I purchase it the navigation system physically looks identical to the one in my 20/20 Toyota Tundra. In many ways it is the same. But where it is vastly different and inferior is the recognition of voice commands. To put a bluntly it's a dumb/ un educated system.Compared to my 20/20 tundra. On my Tundra I can say any place and it will typically recognize it even if it's a restaurant that's a one-of-a-kind destination. On the Lexus you can say something like a Pizza Hut and it'll just say pardon ,pardon very aggravating. It seems typically for a Lexus you have to know a physical address . Then it will get you to that address but that's an extra step where you have to look up and address and your phone . That should not be necessary . Other than that I am fine with the size of the screen and everything else with the system. It recognizes my phone every time I get in and out. I do not want to bother putting in a whole new system just for navigation so what I am wondering is there is app SOFTWARE upgrade of some sort to educate this system., possibly inserting a app software from the 2020 Tundra for example ...keep in mind,it's not just a matter of my voice articulation because I reprogrammed it over and over to recognize my particular speech pattern it didn't make it difference..thanks

 

The answer is no, there is no software upgrade. The issue is that the Nav system on the GX remained unchanged since 2010. In 2022 the system was modernized.

 

I'm not a computer gig but I'm hoping that somewhere somehow someone figured out how to put the software from a Toyota Tundra into the into the Lexus GX 460. They're both made by Toyota in the year 2020 they look identical but the damn software is different and the one in Lexus sucks to be blunt

 

The simplest approach is to install one of the kits to upgrade to carplay/android auto. Lots of previous discussions here in the forum.

If a software patch was so easy, someone would have offered it by now.

 

**** well I was hoping not to have to add any kind of Chinese crap to my nice Japanese vehicle. And I'm sure as heck not going to rip my Dash all apart to have a bigger screen as GX Bob had done... that guy is torn his Dash apart so many times he can do with his eyes closed. I'm not putting him down but I'm not going through all that sorry. I don't have a problem with my eight and a half inch screen. I don't need to have a tablet blocking my view of the road. Too much work and once again you end up with the Chinese piece of crap.. like I said I'm not a computer geek but I'm willing to bet that the program could be changed Even if they just duplicated what's in the 2020 Tundra Navigation system..the tundra is so much more Intelligent I should say . If someone were to figure that out and then Download that onto a Flash drive I'm sure they can make a bundle Selling it

 

The Beatsonic and Hamilton car play system for the GX retains the stock dash appearance.

Here is the Beatsonic installinstallation.

....... so I took a quick look at the beat Sonic install video. But I had seen that before. I had also seen GX Bob install that before. I don't want to go through all that I am perfectly happy with my setup other than the ignorant navigation,AI robot who is incapable of finding anything without using an address. One thing I have against this new setup that you suggest me installing is the fact that you have to have a cell phone when using that. On my 20/20 GX and my 2020 tundra you do not have to have your cell phone with you, navigation still works. The only thing you need your cell phone is technically is to get into your contacts. Also I don't really see any advantage to installing this unit. Both of my vehicles recognize my cell phone the minute I turn on the vehicle. They both have a decent navigation once you get it to understand where you want to go it recognizes my phone and plays my Pandora music Etc I really don't see what you're getting by installing that Android auto play setup. Mine has everything you would need. I don't need to read my messages on my screen that's not what a car is all about

 

This system would get you Android Auto/Apple CarPlay which didn’t make it to the GX until 2022. Tundra got it in 2020.

There is not a simple re-flash of head unit. Most who go aftermarket don’t see value in OEM head units and only go 3rd party so very little if any interest in anyone doing some homebrew programming/hacking of existing head units. These often proprietary OEM systems are also pretty locked down and not really setup for adhoc tinkering and flashing.

I’m still on my stock ‘12 head unit but will likely replace with something at some point.

 

***** thanks for the response but the only difference I see between my 2020 gx460 and my 2020 Toyota Tundra Crewmax is that on the gx460 I don't know how else to put it but the navigation is a bit of a ninny. Like I said in the original quote I can say the name of a one-off restaurant that is a restaurant that there is only one of them in the country and my Tundra will tell me exactly where it is. The GX will just keep saying pardon pardon even when I ask for some place like Pizza Hut where there's Pizza Huts everywhere most times it doesn't even know what Pizza Hut is. So why the difference? And as far as Android auto I really don't see what I'm missing. Like I said mine hooks up Bluetooth right to my phone every time I turn on the vehicle. The map works fine if you put an address in the gx. My music plays from my phone via Pandora on to both vehicles I really don't see what I'm missing out on on this so-called upgrade to Android auto. What is the difference with Android auto what will I gain? If it's just being able to read my emails and messages on the display I don't need that in a vehicle that's more of a nuisance than anything. And once again I will lose the ability to have navigation if I don't have my phone with me. That's a big negative in my mind.

 

Sorry.. I don’t have anything to add. Unfortunately stock system is what it is.

Not aware of any mods to increase voice recognition accuracy other than something that ties into Apple CarPlay/Android Auto for further processing the head unit in 460 can’t handle.

Looking around even though Denso based units I think the 2020 Tundra and GX 460 do not use same processor or OS. This would further negate ease of simple re-flash.

 

okay thanks again I guess I am Sol on that issue. I will have to continue bringing my phone with me and putting in addresses. It works that way okay. I would assume that the system would work exactly the same between the GX and the tundra but it doesn't. The GX is just plain ignorant. Nothing pisses you off worse than speaking clearly and the damn thing keeps saying pardon pardon

 

maybe you could answer me this one thing. What is the big deal about Android auto versus what I have. It seems like I have everything other than the damn thing not being able to understand English! LOL. It's like it's from 1910 and there weren't any Pizza Huts around etc. What do you actually gain with Android auto that I don't already have?

 

Make sure you don't have your center vents pointing up and blowing air - the microphone is directly above and this always results in a failure (for me) in using voice anything.

One of the larger benefits is your voice assistant shifts to your phone assistant and apps. So for an Apple device, saying "Hey Siri - get me directions to the closest Sunoco gas station" means my phone figures all that out, opens Maps and finds a route based on my preferences, and then begins relaying it through the sound system and showing the map and route on screen. The on screen component is the real differentiator vs having your phone in your pocket / a holder with the screen on - the screen components are (somewhat) optimized for driving, so big icons, maps pop up front and center, etc. It's intended to be more convenient than pulling your phone out and looking at it / driving distracted.
