Can. Not an issue at all. But need to set the HU bluetooth to connect with the phone that you want to use Android Auto / Waze. Not just connect the cable only.
Extremely subjective. Can be 0km (idling 100% of the time) to 850km (constant speed on the highway at 90-110km/h). Average is 550km in my case.
Both do police report. Take note of his IC and Number Plate. Time and place of accident. Take photos. If you kena hit, and not your fault, you won't be summoned by the police.

Go to the Police Traffic Station for the accident location. Meet the Investigating Officer - ask him nicely to do the Traffic Accident report quickly - may need to grease hands a bit around RM50 to get it immediately. If not, may take up to 2 weeks.

After that, go to your preferred Honda SC and give them your police report, Traffic Accident Report by the IO, your insurance covernote. Ask to do OD-KFK.

If your car is OK, just use it for the time being while the insurance processing takes place - about 1-2 weeks. When the parts are available, bring in your car for repairs. If your car is drivable, I highly recommend you to not leave your car there for too long. Better use it while the insurance is processing and parts are all available.
Grats! It's nice to see that lots of people getting their Civics soon!
