But for an e53...you can add mirror with HOMELINK buttons or auto dimming because they only require 12volt power and are independently contained in the mirror. Those features don't communicate with a control module somewhere else in the com-bus.

If you have an e70...again the HOMELINK and auto dim is located in the mirror, so only 12 volts needed to operate...which should be already in wiring harness. The side mirrors though...will not dim if they aren't EC and connected to the interior mirror through the wiring harness running to the door (or however the e70 sends data over its com-bus).

If you have an e70...then some of the options mentioned in this thread like lane departure and highbeam assist may require more since it involves communication with other components outside the mirror or components located on the windshield (rain & light sensors).

There is no adaptive cruise control or lane assist or speed limit info in an E70 2008. The driver assistance package came much later.

Lane assist came later...but active cruise control was already before 2008! You can see on older dashboards in the middle two cars blinking for acc! You can watch on youtube how works 1st generation acc on 7er series! One video is from NL and Russia if I remember correctly!

Remember...some options where not available/offered in the USA market whereas they were available in Europe and other markets. ACC is one of them...it was offered in Europe long before here in the states...which is what Gatojurko is probably referring to (plus he's in Latvia). :)

Here's a video of Edwin (from the Netherlands) showing an e38 7 series how ACC worked in that model. Again, the US market didn't have this option...but even back during the days of the e38 7 series...Europe did have active cruise control (click link to watch short 3 min video): https://youtu.be/vO5AdLOXeWs
