[Android Head-Units] skezza:
Looks like I'm going to be the crash test dummy for this unit then. So I'll give my thoughts so far:

Audio Quality - Good. Very good actually considering it's a cheap aftermarket jobby. I've not had one that wasn't a Kenwood or Pioneer sound this good. My Erisin was okay, but nothing on this. The Amplifier app (which is a really a glorified Equalizer) allows a fair amount of twiddling, and I used the optimum settings that I was given by a BMW expert and my word, it blows the OEM radio out the water. Great start.

Screen Quality - It is what it is. Its clearly not high def but then they don't claim to be. It's clear enough though and when navigating earlier I had no problem.

Touch Screen - Jury is still out. I've had a few occasions where taps wouldn't register, but you can never tell if its the CPU lagging or not. Other than that, it seems fine.

Wi-Fi - I was sceptical of how this would perform, as it's one of the biggest complaints on these forums. No problems so far though. Connected perfectly to my phone hotspot and I listened with pleasure to Spotify for a good half an hour.

Installation - Easy enough. There is a surprising amount of wiring though so you need to get a bit inventive to get it fully recessed into the dash.

Does it need the yellow wire to the battery or fuse box? Well, I'm not sure. I found the setting I spoke about above, and so far it does appear to be preserving settings correctly. The only thing that is lost is the clock so far, but the clock is automatically picked up from GPS, so it's possibly a none issue.

Bluetooth A2DP - Jury's out. I tried it with YouTube on my phone and felt it sounded a bit thin, but then music on YouTube always sounds a bit dull and lifeless I find. I really need to use Spotify, but then Spotify works well on the unit, so there's no point.............

Bluetooth Calls - Only made one. Positive feedback though. The person on the other end said it was clear and that's always good. My end, well it wasn't as good as my previous Kenwood, but it was clear enough.

Reversing Sensor Integration - Game changer. It's brilliant. I don't have the camera, and I really can't be arsed to fit one. It's a shame I can't disable the stupid triangle that appears informing you that no camera is present, because the unit displays a car with coloured sensors on the back and that's top draw. Very impressed.

I skipped out on the tyre pressure monitoring, but I've got the DAB antenna and hopefully a piece of kit that will make DAB work with my OEM aerial, coming all the way from Germany.

I now need to resolve a few issues with installation. I wanted to route the USB cables and what not to the glovebox, but how the hell I'm supposed to do that I am not sure. I will get onto a BM forum and find out. I will post some photos up when I'm finished. Also, you do have to file a bit of the climate control part, so it fits smooth. Currently, I've wedged it in without the surround but it looks a bit cruddy, so I will do that probably at the weekend.

Current unit issues I am trying to resolve:

- Cannot get the steering wheel app to work at all. The steering buttons work, perfectly fine, but the actual app itself does nothing, so I cannot configure the voice setting for example, to open OK Google.

- FM Radio is dreadful. It was never good to begin with, but it's horrific now.

- Making the previous audio source come back after a cold boot.
