Looks good! I have the same basic setup with a 10” android tablet, mine gets internet through my phones “hotspot”. A tablet is way better\more use than the i-drive system imo. Good job!!
The only problem with the velcro tape is if you live somewhere that gets really hot in the summer, the adhesive will slowly melt off the ruler, but as long as you change it out every couple weeks it should be fine. A couple times during the summer I opened my door to find my tablet fallen over laying on the shifter lol
