Gilly;

When I bought my ML, it didn't have the option package which included the trip computer.

Subsequent investigation indicates that this is a plug 'n play retrofit with the only mod required being a cut in the smoked plastic window to allow the trip computer readout to be seen.

Do you have pricing on the following parts:

Trip Computer
Part Name: Trip C 116
Part #: 163-540-64-11

Any thoughts on doing an installation like this?

Thanks,
Elmer
