Seeking help with Android head until install

Hello everyone,

Firstly thank you in advance for taking the time to read this post and offer any help, I really appreciate it.

I purchased a brand new Android head unit from eBay for my 2011 Prius. Unfortunately, it arrived with no installation documentation, and the seller has been less than helpful, this is my first radio install and I can't seem to locate any brand name or documentation for this head unit. My Prius is a base model 2011 without the JBL system. Only 2 of the radio connectors connect to the car wiring harness, I don't know what the other 2 connectors on the car wiring harness do, but feel as though they serve some kind of functionality as they were connected to the stock radio. The 3 connectors I'm holding belong to the radio wiring harness and don't fit any of the connectors on the cars' wiring harness. There are also open ended wires and I don't know what to do with those. I have included all possible photos in hopes that they will better help illustrate my situation. Hopefully, someone with more knowledge will kindly chime in and offer guidance or can point me toward installation documentation as I primarily don't want to damage anything in regard to the electrical system of the car.

Thank you again for your time and any help provided, I really appreciate it.

 

Thank you for your reply. I, unfortunately, don't know what you mean by "NAB system" this is all new to me. I tried to include links to the ebay listing as well as a video I filmed of the wiring harness. However, I wasn't able to include those links in this post as it would not let me do so.

2 of the connectors on the new radio wiring hardness connect to 2 of the connectors on the cars' wiring harness, leaving 2 connectors on the car vacant. I did notice on the eBay listing it does list out the various connectors on the radio wiring harness, it shows that connectors 7 and 8 are for steering wheel control, however, those connectors do not fit my car so I assume I will not have steering wheel controls. I haven't hooked up the new radio or powered it on simply because I didn't want to dive into something I didn't yet fully understand. Again I was expecting there to be installation documentation included. With all that said I have a sinking feeling that I'll probably end up returning this unit, unfortunately.

 

I am aware, I am new to forums in general and I posted this in two separate areas, for some reason this one got moved to this area even though I had already posted here. I don't know how to delete the old one.

 

It looks like I will have 2 unused connectors, I simply didn't know if that was normal. My stock head unit has XM built in but I don't use it.I dont have the BT microphone either. Would you happen to know what the unused connectors go to from looking at the photo i provided with the 2 of them already connected?

 

oh okay, yes it has NAV and supposedly supports Apple Car play & Andriod Auto. But I haven't yet hooked up the radio to confirm this. Here is a link to the eBay listing, maybe it'll give you further insight into the head unit. https://www.ebay.com/itm/394261041897?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=vzB_M7ERSQu&sssrc=2349624&ssuid=2goad4QETq-&var=&widget_ver=artemis&media=COPY
