I am not sure if the " orange corner delete" is covered in details in this thread, but just know that they can not be turned off (the way the DRLs can be) and as you will see in some of the DIY threads, it is not a 2 minute job... and to tell you the truth I am still looking for a very clear description on this very topic.
I wish that Atny286 would get back on-line to let us know...
Concerning your question related to the display in kmh... I believe that Atny286 covered this topic in his reply of 10-06-2009... but long story short, you can swap the US cluster by the Euro one and as long as you switch to the Canadian settings (ie, in km) all should be ok.
