I paid $1500 for the DNX7120, Sirius, Adiovox license plate frame cam, and all the harness's plus install at my local Tweeters.
They also hooked up my subs
I would have done the install myself but with my wife in the hospital for the last 6 weeks and me having to juggle taking care our 1 year old baby and work I didn't have the time.
they used all of the metra kits and everything seems to work fine.
It is a great unit and they hooked up my in dash DVD (which is in the onstar location so i now have 2 sources for DVD both for the front monitor as well as the rear monitors.
with this setup we can watch the Head unit on all monitors, watch the rear on all monitors or a combination of the 2 DVD units.
This Unit rocks.
and they were nice enough to bypass the parking brake (well they didnt bypass it what they did was left enough of the parking brake wire and a ground wire dangle just below the dash so i could connect the 2 myself they didnt want to be held liable for that part of the install, so i simply connected the 2 wires and presto all of the capabilities work while i am driving.)
