Hi All,

First time OP, long time reader.

Thanks to those who have written and contributed to the FAQ/DIY threads on the Sat-nav retrofitting threads. They have been an invaluable source of information and have been great so far

I'm facing an issue however. After completing the retrofit, and modifying the harnesses. The Audio/Display/Climate Control screens work fine. But the navigation/destination screens are blank (or white and black vertical lines if I switch between modes)

I also do not see the "I Agree" screen after the lexus logo on startup

If it helps, i've gone from a non-nav, to a ML Nav screen (but using the original CD Player instead of the ML DVD unit)

Any idea on how to get the NAV screen working?
