This is my first post. I have a 2003 Yukon XL with a z1 installed , back up camera ,blue tooth, and bypass. I had circuit city install . (big mistake)

They had my car for 4 days. When i picked it up the navigation antena was not even installed. They never told me because i had a bose system i needed a bose adapter so chime is really loud and radio stations have poor reception. I have to bring it back on wednesday when the part comes in.
The back up camera works only in map mode not when i put veh in reverse. Is there a setting for this or did they not hook it up right. Also at night the camera is very dark the night vision does not work .. Any help would be greatly appreciated..
I WISH I WOULD HAVE FOUND THIS SITE BEFORE I HAD Z1 INSTALLED. THERE ARE SOME VERY SMART AND HELPFUL PEOPLE IN HERE. YOU GUYS ARE AWSEMOE..
THANK YOU IN ANVANCE

Sorry you had such a bad experience with your install. Now lets get down to the nitty gritty. The interface they used to integrate the bose system has a volume control for the door chime. Have them turn it down. As far as the rear camera only working in map mode, there's 2 possible reasons for that. 1 they didn't hook up the reverse wire. To check that in the navi menu hit settings. On the bottom of the screen that shows up it says "back signal" with the truck not in reverse that should say low. When the truck is in reverse it should say High. If it doesn't change then tell them to hook up the reverse wire, not like it's hard to get to. The other possibility is that the z1 isn't set up to automatically display the backup camera when you put the truck into reverse. To fix that do the following (copied directly from the z1 manual)
1 Touch [Camera Input] in the System Settings
menu.
2 Touch [On] to turn rear view camera setting
on.
❒ Unless this setting is [On], you cannot
switch to Rear View mode.
3 Touch [Polarity] to select an appropriate
setting for polarity.
Each time you touch [Polarity] switches
between the following polarity:
• Battery — When the polarity of the connected
lead is positive while the shift lever
is in the REVERSE ® position
• GND — When the polarity of the connected
lead is negative while the shift lever is in the
REVERSE ® position
Now as far as the camera not working properly at night, which camera did they put in?
