hi all

Im new to the forum, joined because i just bought a new to me f90bt. 

I have not connected the vss/speed wire yet.

My avic keeps shutting off and rebooting after it displays the parking break is not connected properly message

i have it independanly grounded -that GREEN wire.   but the message still pops ups when i drive and then the unit shuts down.

still running some old version 1.0  

Another problem is the back up camera shows up very light.  As in, can i adjust the rearview screen to darken a bit.  It just look like someone has a light up to the camera. I have tried 2 different cameras so far and the same image shows up.

I have googled these issues and tried a few things and I'm still having the same problems.

thanks

Corrected my hardware bypass. with the mute wire. i also noticed i need a new main harness, the power and ground wires are loose. temp fixed this today and i ordered a new harness. 

Unit works up until i start driving and then it randomly reboots. 

I purchase a 4.0 upgrade/software fix from ebay from the seller Anttid. seems to have good reviews even on this sight.  

can anyone help me out with what i can do to try to fix the reboots randomness 

thanks
