So I had the opportunity to install one of these into my old X5 and made a video guide. It's still unlisted but wanted to get some input on it before making it public. Let me know what you think. Do I need to add something? Did I forget something? Get something wrong? Etc.
It's a little lengthy but the install of one of these in a factory navigation truck is a bit lengthy so I suppose it's fitting. I am not a videographer so was just trying to get the information across in a way that was understandable. It's not a pretty video at all. Also, let me know if you'd like a PDF guide/thread like my Avin Avant 2 install thread. I would be able to do it fairly easily as most of the pictures and descriptions could be recycled with a few caveats.
