The question is, do you have a video signal on the front monitor when the car is standing still? If that´s the case you have two possibilities to get video on the front screen at speeds above 2 mph.
1.) You can buy a little electronic-box which "disables" the velocity signal. It´s quite easy to install. You just have to remove the monitor and modify two plugs. I can send you the manual (pdf-file, unfortunately in german language, but well illustrated) if you like. I didn´t find any of those boxes on ebay.com, but you can find them on ebay.de.
2.) You can modify the car´s software. Therefore the car must have a tv tuner installed. This service is also offered on ebay.de.
I guess you´ll also find this kind of services in Canada.
One more thing: these BMW alloy rims (design 128) are looking really amazing.
You can´t find a better rim for the E65/E66 imho. Congratulations.
