Hey guys new here, was asked to join for help from a member on e46.
I got a modified ashtray panel where the concealed display gets tucked in with a cut on panel that fits over it. There is a switch on that panel that allows me to power on both the concealed display and main unit. So basically I can just leave the main unit on always. I have the main unit hung right below the rear view mirror. I tried to hardwire it up this past saturday.
Basically I ran a line to the main unit, snaked it from the headliner down the A pillar, through the glove box and into the concealed display. Ran another telephone line from concealed display to the hardwire kit provided by v1. The hardwire power plug is tucked in right beneath the shifter. I must mention that the modified ashtray has a switch with 2 lines to power it. I hooked up the red line to one of these that are on the ash tray panel switch. The ground wire was attached to a metal bracket on the shifter plate. The final line from ash tray panel switch (the other black wire I mentioned) was tapped into the brown/green wire for the cigarette lighter.
I tried everything when powering it on and everything works. But I had 2 problems that I needed to ask.
1. I get no power when my headlight switch is at off. However if I have it on auto, the entire unit turns on. What other options do i have to tap into for power?
2. I get flickering on the concealed display, I'm no whiz on wiring, but I'm thinking I have a bad ground and need to relocate that wire to a better ground on the chasis.
Thank you in advance for the help guys. I couldn't get any help from my regular car forum.
05 m3 if that helps....forgot to mention vehicle.
