First, I have done a search and come up dry. Second, I realize this is much more than a software upgrade or screen swap.

For those of you familiar with BMWs, of which I am sure there are many, there is an aftermarket company called Bimmerretrofit that allows older model BMW owners to upgrade their iDrive systems to the latest and greatest - oftentimes involving installation of new hardware and software/some coding. I have looked around and not found anything like this for LR aside from the NaviPlus solution but that only nets you the Apple CarPlay functionality.

I am not certain what other changes happened to the l494 with regards to the onboard communications systems, etc. but, at a high level, I was curious if it is be possible to retrofit a 2017 infotainment system into a 2015.

The approach I was thinking of taking was finding a totaled 2017 l494, removing all the infotainment modules, screen, etc. and installing them into the 2015. I am sure it is not as easy as plug and play but just curious if anyone had insight into whether or not there are differences in the wiring? What kind of programming would be required?


Many will probably chime in and say just buy a new car but I like the one I have, a loire blue HSE with pretty much all the goodies including the twin speed Tx case, and this is more of a project to mess around with. If it is impossible its not the end of the world for me.

Hi amm,
I just went from a 2014 RRS to a 2017 and the difference in the infotainment is HUGE! So, if you can pull it off, it’s absolutely worth it.

I’m in technology so yours is a question I pondered for a long time. Here’s where I was with my thinking…


Like you said, first you’d need to find the head unit. I looked on eBay regularly and always came up empty-handed. I also looked on various junk yards with the same results. But, assuming you are able to find the 2017 unit, next would be fit.


The first place I looked was a parts website to see what components were associated with each system. Here’s what I found for the 14-16 MY:


https://parts.landroverpalmbeach.com/a/Land-Rover_2014_Range-Rover-Sport-Supercharged-50L-V8/_56655_6475335/ENTERTAINMENT-SYSTEM-COMPONENTS-ELECTRICAL/7122295.html



And for the 2017 MY


https://parts.landroverpalmbeach.com/a/Land-Rover_2017_Range-Rover-Sport-Supercharged-50L-V8/_56655_6475335/ENTERTAINMENT-SYSTEM-COMPONENTS-ELECTRICAL/7122295.html



Even though we both know the screens look very different, it seems that the number components are the same: screen, head unit, bracket, etc. So, on that end I would venture to assume that on some level the brackets that hold the screen and radio unit should be interchangeable.


Next was trying to find out what the unit actually looked like behind the trim. I found this video on how to remove the head unit on 2014-2016 MY RRS: https://www.youtube.com/watch?v=A2PfIKrL-3s. Again, you’ll see the screws that hold down the screen are set for the width of the screen. Because the 2017 is so much wider, that whole bracket would have to be replaced.


Then there’s the question of the radio unit. The parts drawing shows them being the same size, but they also show the screen being the same size and we know they are not. I was never able to find an answer.


Finally, as it related to fit, you’ll notice that the plastic trim around your screen is different than the one on the 17s. Yours has a “step-down” from the side touch controls to the screen. The 17 is one continuous piece.

So, I wanted to find out if it was a matter of replacing the trim or if the whole piece had to be replaced. Unfortunately, it’s the whole piece. Take a look here


https://parts.landroverpalmbeach.com/a/Land-Rover_2017_Range-Rover-Sport-Supercharged-50L-V8/_51505_6477895/INSTRUMENT-PANEL-COMPONENTS/7122525.html


Then there was the question of connectors. Would they match, and would they work? Here’s my theory based on nothing other than experience in the technology industry.


It doesn’t matter if the connectors between the screen and the radio unit are different, you have to replace both. The connectors to the center console with the USB ports will be different because the 2017 has different components in the console (USB, HDMI, and SIM). Again, you have to replace both so it doesn’t matter.


And then, there’s the connector to the car’s harness. This has been debated a lot on other threads. I was really tempted to believe that they would match, but I don’t think they will because of one single difference that would make them different. MY 2017 supports 3G cellular data. So, the system must connect to the cellular antenna. IMHO that alone would not make the two connectors swappable.


Then of course, there’s programming. All the functionality on both systems interacts in the same way with the car. Steering wheel controls and climate seat buttons are the same and function the same way. But, I’m sure there would be some programming required.


Next is the consideration of price. Here are the things you’ll need to buy and my guess on what you can expect to pay:

- Screen $500 (used)

- Head unit $500 (used)
- Center console components $300 (used)

- Brackets $400 (new)

- Dashboard trim $1000 (new)
- Does not include cost of cellular antenna and all required wiring


Finally you have to keep warranty in mind. Assuming your car is still under warranty, by making such a drastic change to the car, you are essentially voiding the warranty. The dealer might not hold you to it if the repair is not related to the car’s electronics (let’s say the timing chain goes bad), but any repair remotely related to electronics (headlights, air suspension, power windows, A/C, etc.) I will venture to say that they will tell you that they will not repair it under warranty.


So, there you have it! Hope this helps on your decision. Keep us posted :)

If it is anything like the full-size, going to ICTP from ICT would be insanely expensive. The bus system on the ICTP vehicles is different and many components are not compatible.

Yeah I'd love to upgrade mine as well but the warranty issue is a non-starter for me. Price too.

Guys,

Thanks for the information, WOW! this is great information. This looks doable but perhaps in the future when prices on parts come down and I am no longer DD'ing this RRS. I have coded things on BMWs but there is a large community out there for that so this would require lots of experimenting.

thanks again!

DJJ, anytime! We all have curious minds around here and sometimes these kinds of questions are met with short and snappy "can't be done" answers. I wanted to take the time and shed some light on a topic that's been discussed quite a bit.

Yeah, super awesome! This is what auto forums are all about!!! Learning along the way, sharing with each other, and continuing to build our knowledge base for future owners and RR lovers :) Appreciate you very much!!! Now, someone just has to dive in...one day, hopefully, we'll know the end-all-be-all answer to this :)
