Welcome along Joel. If you get your questionnaire back to Tim and get full access to the site there is a lot of information regarding upgrades to the Hi Line system. Most replacement units come from Sean (aka Radioguy) on the 75/ZT OC forum here:
What car have you got? What are the last three digits of your VIN? Any photos?

Looks like an older version of Navall. Is it android or windows. Get former. If camera has got two long plastic arms don't use. My ztr has a near camera only just under tailgate handle cost abot £20 on eBay.
Have photos somewhere. Fitting not too bad if you have trim tools and go gently. Knowing your wires ans tge order of removal of tge centre column faceplates helps. All on our fora in detail.
Good luck. It should taye a dash cam as well if you want a fixed one at almost no money as well.
Good hunting.
