It has been reported that the C63 has a feature that turns the MFD to red to act as a shift light. So that got me thinking... Does anybody know how to make the MFD turn red other than pressing on the e-brake or some other warning. It would be really cool if you can program something in the car to do that!

Any electrical engineers out there?!!!

 

would be cool if it turn red when you doing speeds like 75+ mph

 

or if you get above a certain RPM

 

My portable GPS can be set to beep annoyingly at a preset speeds on certain roads, for exampe you can set it to beep at 50mph on secondary roads and 75mph on freeway, hmm, maybe if I mount it permanently in my kid's SLK it would cut down on her speeding, and if I had a way to mute the radio above 75mph that would definately make her stop. And even better, hook up a cell phone signal jammer that would block all calls in her car above 75mph, now that would be icing on the cake. OK, who can make me one of these?

 

Well! That was kinda assumed thats what it would do... you know a shift light... hence the title of the thread!!! LOL!
