F-type navigator's map blacked out
Hello,
I have just tuned my F-type with the Velocity group. The car is now a beast! Problem is that since this mod the map in the navigator disappeared (see pic). Before the mod, I was able to visualize the map. Somehow the instructions are there (the navigator says things like "like turn left", "right" etc), so the navigator knows where it is, but the map does not appear.
The tuner told me that their mod device can only communicate with my engine module. Their device would not be able to communicate with the navigation module nor change any of its settings. I believe him, but I still have this problem and I was wondering if anyone of you have ever had similar problems. Another solution I had in mind, if nothing works, is to buy the updated maps at Jaguar (https://jaguar.navigation.com/produc...S/JaguarNA/USD). It is a system to update the map via USB. I imagine the USB map update should not interfere with the engine ecu mod, right? But it is overpriced

Mine did exactly the same thing almost exactly two years ago and it hasn't happened since (several others said exactly the same happend to them too). It just came back to normal by itself after the car was shut down for several hours and restarted. I found later the nav system doesn't really completely shut down/forget everything for at least an hour so shutting down and restarting immediately didn't make the issue go away.
You might also check to make sure the battery is ok.

I've never had any side-effects from the device used for the VAP tuning. I had some issues with satellite radio reception when the antenna was failing (replaced under warranty). I did have my nav screen mysteriously go blank once, but I rarely use it and it "got better" on its own.
Perhaps a "battery module reset" would work (disconnect battery for ~15 seconds).

mmm, interesting. Maybe I damaged it by using the "recond" option on my CTEK battery tender (just before I did the VAP tuning). It is odd, but whatever. The car has been shout down for several hours already and I did the batter module rest as suggested but I still have the problem. However, this discussion helps--- knowing that some of you had the same problem and then it solved by itself after some time gives me hope. I very seldom use that map anyhow, so I do not really care much.

It usually take 5 restarts for me as well to clean all the error codes after the tuning. But after that, I have driven my car for almost a week, so my car should be over 15 restarts by now. Oh well, those maps suck anyhow. Let's just hope they come back in case I want to sell the car. At this point I have to assume it was not the tune but a coincidence --- I seldom use the maps so maybe they stopped working few days before or after the tuning. Mysteries of Jag technology!
By the way, and off-topics -- the VAP tune is amazing. Worth it!

There is a video cable that runs from the head unit at the rear of the centre console, to the touchscreen, that is for the map image.
I've seen it a few times in other JLR models with the same system, where the map image goes black, because the video signal is missing.
As far as I've been able to tell, it's a fault with the video output from the head unit.
Could be just bad luck / coincidence that this coincided with loading the tune.
All you can try is disconnecting the battery, "hard reset". But that may only fix it for one ignition cycle....

I appreciate! I did the hard reset, but no change on the screen. It is so odd, the navigator technically works (it tells me when to turn) but no map on the background--it is all black. I will wait a few weeks to see if it will get fix by itself. I am not even sure a map update would fix the problem if, as you hypothesized, is a hardware issue

I wish! It has been several months, and the problem is still there. Not a battery problem, not a tune problem. The only guess I have is that I have installed a back up camera and maybe the guy who installed it messed up the cables on my NAV. However, giving that many others have this problem, it is probably something else. Not sure how to solve it. I would buy updated maps to try to fix it, but they are way too expensive for just an experiment

Going from your first photo you have information displayed around the edges that are being generated by the nav unit. This can only be displayed properly if the cable between your nav unit and head unit is working correctly so it is not a cable issue. It suggests to me you have either software corruption in the nav or a bad circuit some where. I think I read somewhere that there constant power to the nav. You could try hard resetting by unplugging the nav or alternative disconnecting the battery for ?1 hr . Failing this you could try reflashing the nav unit via USB

Before buying new maps, try UAD's Car Play / Android Auto replacement for your NAV unit. Best thing I ever did... I hardly use the stock interface at all now. Easy install and a complete game changer for the car.

Thanks for the answer. What you say makes sense.
I will try to unplug the battery for 1 hour.
In case it doesn't work, how can I relflash the navigatior? Should I buy new maps?
Thanks

I just installed a backup camera --do you think this software will be compatible with the camera?
Many thanks!

Good suggestion by tkwesa. I would also do this before buying new maps. i have the joyeauto unit which is the same as UAD. You lose the factory nav option (which doesnt work for you anyways) and it then becomes the pathway into the carplay adaptor from which you can use whatever map app you like which is way better than before. Also wireless to your phone. Plenty of threads on install but super easy as all plug and play(ie no splicing into looms)

Very easy install and they have support for backup cameras, even aftermarket ones.
