Just installed one of these in my car (disclosure: I work for The Warehouse and get a staff discount on things like this).

The American HiFi AHF-930 is a budget double din head unit with a touch screen and no disc player.

Prior to purchase I could only Google the basic specs so I thought I'd put this here in case someone else is interested:

- Doesn't use the normal ISO plugs like my previous aftermarket head unit, so wiring job required
- Wires include a bunch of accessories like handbrake, brake, reverse and steering wheel controls
- In my case, the steering wheel control wires allow my Holden Commodore VX to control the unit (a nice surprise).
This is done by training the head unit - simply hold down a steering wheel control and assign it to the relevant function (Mode, Next, Previous, Vol+, Vol-, Mute, Answer Phone, Disconnect Phone)
- It accepts a 64GB Adata microSD card
- It handles 720p MP4 video from the microSD slot (haven't tested USB yet though)
- Using the external microphone (which plugs into the rear), it was long enough to be routed to the top of the driver's side front pillar (but no further) and Bluetooth calling works well. Only noticed afterwards there appears to be a microphone in the front panel so not sure of its capabilities.

Any questions post here

Does it take a reversing camera?

Will it connect to wireless tyre pressure sensors?

Yes, it takes a reversing camera. There is actually an AHF branded one available as well.

I'm not 100% sure but I doubt it connects to wireless tyre pressure sensors.
I think the reversing/brake wires are to do with video input (either engaging the reversing camera video feed or cutting out the video altogether if the handbrake isn't on).
I can't confirm as I don't have these wires connected.
Still there is nothing in the menus about tyres etc so I don't think there will be any functionality available there.

I've been wondering whether it was possible to get something like this cheaply. Will look in to it. Thanks for the info.

Thanks for the reply. I've been looking for a double-din unit for my Pajero, which is our main tow wagon.

I'm keen to get something with tyre monitoring and a reverse cam.

There is a standard wireless tyre pressure sender system. The senders can screw onto the the dust cap threads on the tyre valves valves so it's easy to swap between wagon and trailer.

I've seen a few android head-units with the tyre monitoring system built in, but they get mixed reviews.

I bought one of these, it's all going OK but there is a bizarre problem with Bluetooth. If a private number calls you, you can't answer a call, it doesn't even acknowledge the call exists, if you answer by pressing the answer on the phone handset the call works fine, its just odd it doesn't know there is an incoming call on the cars headset. It's very annoying as you can't answer the calls using the headset like you can a call from another normal phone number without having the number private.

Other than that, the headset seems reasonable.

I had the external bluetooth microphone plugged in, I didn't find it any better so I disconnected it and use the built in Microphone now, works just as well so I don't see the point of the external one.

When you say it doesn't "handle" 720p, is this because it struggles to keep up? Have you tried using a class 10 micro-sd card? If not, then the sd card probably wont be able to feed the data quick enough.

One person supports this post

phrunt: I've played 720p content on mine

That answers that one. The unit can do it. Just make sure it is a class 10 micro sd card.

ps, There are a lot of micro-sd's out there that are counterfeit. They tend to be unreliable, and can't sustain the performance they say they can. I personally only use the Samsung branded cards now because of this.

eBay have a whole page dedicated to warning people about the counterfeit cards now because they are so prolific. I wouldn't personally buy any such cards off any auction site as a result.

For me, it seems the head unit is unable to handle the bitrate from my 720p videos, which are all music videos BTW.

My microSD card is actually an Apacer brand, just a budget one from PB Tech but it's a class 10. Don't have a better one to try instead to see if I've gone too cheap, however I've just tested a 32 USB 2.0 stick and the 720p videos don't work for me either - the audio stream is mostly fine but the video just lags and skips. 360p music videos are just fine though. Although having used it for a few days I notice a second or two delay before the sound kicks in - not really a big problem (it's not out of sync)

Well appears I've been doing this wrong all along.
Checked out the files on my PC and I've been downloading 1080p videos instead of 720p.
Having replaced them with the 720p versions they do indeed play just fine.
Might ask a mod if I can edit my first post to correct this.

(Edit - now corrected)

I thought so, as it worked for me.

The unable to answer calls from private numbers is really frustrating me though, it doesn't even know the phones ringing if it comes from a private number, seems so odd... it's gotta be a bug in the software

Not answering private numbers sounds more like a feature to me. Its not something that you can turn off is it?
