If I can find time to sit down with the wiring diagrams I might cook up my own puddle light switch using a custom labeled OEM look switch
CH4x4 Toyota Small Push Switch Sasquatch Lights Symbol
When I bought the Anytime camera kit I ordered the nav option but they only supplied a plain little toggle switch. So I bought this OEM look switch...
.... and modified it internally
Now the illuminated "GPS" letters turn off when I push the button...
... and that enables Nav changes without stopping the 4Runner
If anyone has already researched the puddle light interface let me know. I've searched a little but no hits yet.
