Got the F900 unit installed last night using the Metra GMOS-04 harness.

Two issues:

My door chimes are very loud now. Where do i adjust the volume for this. is it the screw connected to the Metra GMOS-04 harness box itself. if so, i just thought that was a level adjuster for the music just like an adjuster on an amp to make it louder.

Also,

My DVD screen is now smaller than before. it has an inch of black on each side. i put in the same DVD as before the install and the screen was full and not cut off like it is now. Install issue or what??

Thanks in advance,

the gmos 04 has two potentiometers for sound level adjustments (as shown on page 6 of the manual) the one at the top (next to the harness connector) is for audio level adjustment and the one on the side is for chime level adjustment

ok cool

hope this is the last time i pull it out

probably not

still baffled about the darn DVD player screeen too

i will check the connections

thx

dvd is fixed now too

sweet
