MY2007+Update: Please note that the hack below will only work on MY2006 RRS (as well as MY05/06 Disco/LR3 and MY05/06 FFRR) with original navigation data DVD. Later model year satnavs (2007+) were flashed with new firmware, which disabled the 1791 bypass code. MY2010 and later use a completely different (hard drive based) navigation system, and the hack won't work on those models, either.
After several days of testing in my car without any adverse effects, and after receiving positive feedback from a couple of fellow RRS owners, I am happy to announce that I accidentally discovered the seemingly "impossible, nonexistent, unthinkable, undefeatable" hack code to unlock our navigation system controls while the car is in motion.
For those of you already familiar with accessing the Nav diag PIN entry screen, the entry sequence is 1791, OK, Return. For those who don't know what a diag PIN entry screen is, keep reading.
IMPORTANT DISCLAIMER: As always, I am not responsible if ANYTHING AT ALL goes wrong while you are trying this, whether your monitor freezes, your engine won't start or you crash into a large tree... I found the code because I got lucky (and because I spent a few hours scouring the internet for leads/ideas), not because I knew anything more than you guys know. I have no idea whether this hack may create problems down the road, I don't have a clue if it works on every Sport out there (it does on mine and another 2), on LR3s or big RRs with the same Denso nav system as our cars. Don't call/write me for help, because I will not be able to give you any, other than the directions below.
The beauty of the hack is that you can enable it while you start the car or while you are already on the road, and it really takes only a few presses of the touchscreen, maybe 15 seconds total. This beats having to pull over if you or, I sincerely hope, your front passenger wants to enter an address while you are already driving down the highway. The bad news is that the hack is temporary. About two minutes after you turn off the engine, the car's computer will shut down and will take the hack down with it. So, you will have to reenable it whenever you need it. There may be a way to make this hack permanent, but I have not found it (yet) and this is better than nothing, for now. Lexus drivers have to put up with the same hack limitation...
Let's start. First of all, you need to get to the on-road Navigation Menu as shown in picture B below. So, if you are just starting the car, you go to Navigation, acknowledge the obnoxious Land Rover legal dept. by pressing the "Agree" button, and you'll probably get to the map screen shown in picture A. If you are driving, you are most likely already there. Press the lower left Home button to get to the Navigation Menu:
You should now be in the Navigation Menu (if you are moving, some square buttons will be grayed out, but it does not matter.) Press the UPPER CENTER portion of the touchscreen for about 5 seconds (there is an invisible button there), as shown below:
This will eventually bring up the following "secret" Diag PIN entry screen:
Using the touchscreen, enter PIN # 1791 and press OK, like this:
The screen will look again like it did in Picture C. It appears the PIN entry has failed, except that it hasn't... Press the Return arrow on the upper right corner to go back to the Nav Menu:
That's all there is to it. You should now have access to all navigation entry and setup menus, whether you are moving or not, free of charge and with my best Easter wishes...
