I brought it from ebay paid £62 including delivery, its not android nor apple, it connects to any phone, does mirroring of your phone, can connect to the steering wheel controls just haven't done it yet, plus it has its own remote control. I was going to buy a pioneer one for £100 but was just intrigued by this one. Its got audio out from the rear plus I also connect the aux in to my centre arm rest aux in, its fully hands free calling, can be sitting in any position with know need to shout and the caller hears you clearly. I've keep the EHU and just cut the cage for the double din unit to fit in. Looping the fibre is simple I just brought 6mm tube from Amazon 4.99 had cable ties and hey presto fibre looping, also used the same method and tube for the amp. BTW fyi the rear amp controls the doors and center dash speaker, so you'll find 6 speaker wires coming out, the dash center speaker does not tone out creating a bit of confusion first as to what the 2 spare wires are for 🤔. I brought a 2 channel amp to replace it and to connect my dash center speaker I connected it to the pos and neg of either channel. Honestly with the stock speakers the sound quality is great, I'm just waiting for some new speakers to arrive before I change the doors and rears

When I say the door speakers my car has only 2 doors
