The 11.4 screen requires more than CCF editing to retrofit. It requires retrofit programming. We do the retrofit in house. Upper and lower dash trims can be modified to accommodate the screen, however, if you want a perfect OEM fitment, replace the trims.

 

Hi Sarek, do you know what aspects of the 11.4” (or even 13.1”) screen retrofit require programming beyond what the Gap IID tool provides?

I’m not looking for specific programming instructions, but I’m wondering what features are lost, if any, when using only the Gap IID tool in support of this retrofit. For example, when using only the Gap IID tool, is the resolution unmodified from the 10” screen?

On the Defender2.net thread referred to above, the author clarified that using the Gap IID tool was sufficient.

Thanks!

 

I did some research in the past few weeks to figure out how to order parts for retrofitting either the 11.4” or 13.1” screen. Based on reviewing the Summer Automotive videos in which a non-OEM bracket is demonstrated, I reached out to Summer Auto to inquire if I could purchase their retrofit kit without the screen. I had also noticed a similar kit with screen available on Ali Express via Zhous Automotive. After some email back and forth, it became evident that they are the same company.

The good news is that Zhous offered a SKU of parts required including a wiring harness adapter without the screen. I suggest you contact Jeffery, Sales Manager, at sales@zhous.co.uk to get a quote. I have not yet ordered the kit without the screen, but am seriously considering it.

I am super impressed that Summer Auto/Zhous offered a new SKU without the screens based on my inquiry. Talk about flexibility and responsiveness!

The kit appears to be the same for both 11.4” and 13.1”, but one of the brackets might need a slight modification to fit the 13.1” screen. This is mentioned in one of the Summer Auto videos on YouTube.

It’s not yet clear to me if the non-OEM bracket is shaped so that we wouldn’t need to modify the long horizontal dash trim pieces against which the screen rests.

This is the SKU and details Jeffery shared with me:

Product : 13.1 INCH MASSIVE SCREEN RANGE ROVER DESIGN FOR DEFENDER ( EXCEPT FOR THE SCREEN )
Qty: 1 Set
Product No.: Zhous-41
Price: EXW US$420
Express Cost: US$159.4
Total: US$579.4

Here’s the complete kit with screen. The SKU referenced above would subtract the screen:

 

I asked this very same question for my previous 2021 P400SE and the dealership told me thats a hard no - it cannot be retrofitted.

I went ahead and upgraded to a 2023 P400X in March which came with the larger screen - much happier.

 

I wouldn’t expect most dealers to be knowledgeable or perhaps even supportive of retrofits of most kinds.

It’s clear from the available examples that upgrading to the 11.4” screen either DIY or via third party shops is feasible.
