Cost to buy and install dual DVD system? wondering if I'm getting screwed

[cwe6279]

I am looking at the Invision SL Active dual DVD players for a 2009 X5 I ordered recently. The dealership is quoting $2750 plus tax to buy and install the part# 65120440062 (Invision: Grey nevada leather seat-back dual DVD players) partly based on their saying it will take 5 hours to install completely.

I just bought a brand new X5 from them and it seems like this is a bit on the high side considering that. Does anybody know about how much time it should take to install these things? Also, I've seen retail is $1999 but that's retail right? Found resellers online offering as low as $1700, which means they are also making a margin on the units themselves I would guess. As far as I can tell they are maxing out margin on labor and the units which I find very bothersome after spending 60k on a car through them.

As far as labor rates go I've heard they range from about $85-150/hour max but even at $150, a very high rate it seems(?) it doesn't seem like it should come out that high.

Am I being unreasonable?

thanks in advance,
Charles
