GS430SE2

I have a 2004 GS430 (2nd generation) fitted, as is usual, with the Generation 01 navigation system - the one that starts up with this screen:

and which "features" (sic) the Motion Lock on the satnav (where I can't set/change destination and much else while the car is moving) drives me nuts. Lexus is not my Mother. I know.

I tried all the cheats I could find online, tapping various parts of the screen in sequence. One did get me to an information/diagnostics screen, but there was definitely no override capability there

I also tried cutting one of the wires into the centre console (forget which, now) as per forum suggestions, but that too made no difference so I spliced it back.

I then gave up.

Now, years later, I've checked to see what's available, and found this:



This "Beatsonic nt0202" looks suspiciously like a button switch which simply cuts one of the wires in the loom at the back of the centre console. If so, it is unlikely to fix the motion lock.

Is it likely to work on my GS? Thanks in advance for your answers.
