Hello Paul Just an up-date following your observations about the software, I have now been in touch with the Lexus dealer who I bought the car from and their records for the car do not show any modifications carried out to the software or navigation system, so I have to draw a blank there. It is still a mystery and especially as even Lexus Technical are unable to help! Thanks for your suggestions, though, Michael

Hello Paul Thank you for your very interesting post. You may well be right, and coincidentally I was thinking of contacting the Lexus dealer I bought the car from in Chester to see if they are aware of the history of the car in respect of the software. I did know that the car had only one owner and was bought from them from new, so there is a possibility that they may be able to help. As far as why the system suddenly reverted to the split screen, I wonder if the software has inadvertently updated and used the pre- face-lift details. This, however, does not explain why it went to split screen whilst driving! Thanks Michael

Hello Colin Thank you for your suggestion. If only it was that easy! What you have suggested is how it should work, but I cannot get the arrow you mentioned to move as the cursor will not lock on to it! Thanks anyway, Michael

Hello Shahpor Thank you for your post. I am attaching a photo, as requested, of the current screen configuration. Michael

Hello Colin Yes, the extract you have posted from the engineering documentation is what I was also given when I took it into my Lexus dealer, who obtained it from Lexus Head Office Technical Department. The dealer has tried in vain to get the full screen back. Even so, I definitely had the full screen facility prior to this latest blip. I wonder if the previous owner paid for this facility for this car and for some reason ( I would like to know what) it has now reverted to the 2012 spec. Any thoughts? In the meantime, thank you all for your comments, Michael

Hello Shahpor Thanks again for your additional comments. There have been no modifications to the system since I have had the car. I have enjoyed having the full screen for a couple of years since I purchased the car, and then a few months ago, for no apparent reason, it reverted to the split screen! I had not made any adjustments or alterations to any settings - it happned just as I was driving! Prior to this, the split screen only appeared if I used the radio, etc., when the spit screen would appear, disappearing automatically when these functions were closed. Michael

Hello Colin Thanks for that information, Michael

Hello Shapor Many thanks for your response. Unfortunately I don't have any photos of the full screen prior to it changing to split screen. Your comments are interesting, though, and I wonder if there is an up-grade available for my car based on the 2016 facelift which does seem to show the full screen I had. I am in the UK.

I have had my car around 2 years and have benefitted from the full 12.3" screen for normal map use and navigation.The Split screen function appeared when using the radio, for example, but then reverted to full screen after use. In the last couple of months the display screen has diverted permanently to the split screen function and despite trying all the usual instructions I cannot get back the full screen function that I had before. Lexus technicians have also attempted to rectify the issue without success. Lexus " head office" are claiming that the full screen I had is actually not available! Any suggestions please?! I wondered if an up- dated navigation DVD might be the answer.
