I have a number of new Mercedes ML Series Trip Computers A163 540 52 11 I
they have a 630.00 retail price and I'm selling them for 75.00 each with
5.00 for priority shipping.

I have sold over 100 of them on eBay with instructions on how to install it
yourself
in any ML that didn't come from the factory with one . Although they can
also replace
any defective unit that did come with one. To view a tour of the functions
of the overhead onboard computer go to this link

If you would like a 620 kb email with adobe instructions on how to install
the unit please feel free to email me at cousins@kc.rr.com
