Thank you, this is exactly the information I was after. An extra $500 for the dynamic grid lines and overlay equipment plus time to source parts plus coding.
The plug and play bimmertech appears to be a good balance of functionality and cost.
I'll have to wait to get those extra features in a 435i someday
Your modification is a work of art though, nice job!
