New Headunit installed (almost) rear sensors and antena

[Bombers Rule]

Hi i installed a new chinese headunit over the weekend. bought the unit about 18months ago and just been sitting in my garage. Anyway when I pulled out the old unit there were two cables on the bottom left of the unit. I figured one was the antena and I need an adapter to connect it. I just ordered one off ebay

now i need an adapter for the reverse parking sensors. can someone advise what type of adapter to get.
I still need to finish mapping the steering wheel controls but should be no problems. It is also wanting me to be connected for google maps to work. any idea on how I can get maps working offline. Unit is running andriod 5.1.1 Lollipop.

Noticed today that it connects bluetooth to my phones [apple and android] but microphone from above driver head (ceiling light console) is no longer working. Any ideas how to get it working. Finally, I wanted to take out the glove box to run the gps cable up the side trim on the left hand side and not sure how to get it out.

Car is Mondeo MC tdci Wagon 2010. Great car bought it in may 2015 with 141k and done another 60K in it. Tow a small pop up camper trailer with it. Get 800-900km per tank driving it to around town and to work. replaced timing belt at 195km.

Got a few dints and plenty of carpark dints in the door. any ideas on easy ways to fix these.
