I used the Scorche radio install bezel made for the 4runner. unfortunately they only make it in silver so I will go back later and wrap it in carbon fiber vinyl to match the shifter console.
I also wired in a MAESTRO module behind the headunit so all my steering wheel controls work plus you can even program steering wheel buttons to do extra things. Like I programmed my back button on steering wheel if I hold it down for 3 seconds it will pop up on the headunit my Gauges creen. If I hold the next button for 3 seconds it will pop up my tire pressures screen.
It gives you the option to choose from like 20 or 30 types of gause to show on the screen from transmission temps and EGT temps to RPM or even show your 0-60 times or 1/4 mile times.
The other great feature is it lets me program all sorts of vehicle functions on the headunit screen like windows down with key, windows down with remote, doors lock when shifted into drive or into park unlock. Change the door lock beep functions etcc among other things.
I have the Kenwood DMX7704 with the iMaestro. How did you get your tire pressure read out to work? My local says that it cant be done. I get an error message that the headunit cannot communicate with the TPMS system.
What did you do for the GPS and Serius Antennas? Were you able to use the OEM sharkfin. If so, how did you get the piece that goes from Toyota ant to Serius tuner? I know I misspelled Serius.
