[MTCD  Android Head Units Q&A] aeonfluxcapacitor:
Thanks for your update droc.noles :)

Good to know, I'm using that same setting and everything seems to be working as expected (door indicators, AC overlay, tire pressure, mileage).

I should mention I've seen other AHU users complain about the AC overlay being off by a few degrees. That is not the case with this unit. It maps perfectly to the lower display.

Understandable. I've also left my GPS loosely in the glove-box and its working fine as well. I didn't hook the external mic up because early tests showed the built in mic was working well enough with Google Voice and on limited call tests.

I should ask, are you in a US Corolla? I did have to remove some of the plastic to get it to fit into the dash. I saw this same issue mentioned in an Amazon review for a SYGAV unit for a Corolla. It's a bit annoying to spend this much and have to make your own edits but it wasn't terribly involved or risky at least. I wish the US eBay auction would have included this fact though. (We bought the same item/seller it seems)

I'm not having this issue or haven't noticed it yet. I have noticed my WiFi hotspot doesn't always connect when its available. I have to instead move to the WiFi settings screen at which point it sees it and connects.

It can't see my home WiFi from my driveway (parked 10 ft from the house) which is a bit surprising so I haven't been able to test with anything other than my LTE/hotspot bridge with the phone very near the dash. In this case the WiFi seems to work well. I am bummed though that I can't sit in my driveway and preload some songs on Subsonic. I'm curious if attaching a better (longer?) antenna might help.

I'm not having issues here thankfully. Radio and other audio apps work well. The Radio is showing more static on a station I used to not have as much static on however but most other stations are very clear.

I have not attached all the analog AV input cables though (don't have much of a use for them, only attaching the ones required to have the backup camera, any that are completely unused that I didn't need to connect to the HU were left off). I can't help but wonder if maybe if you have yours connected, if any loose connectors aren't making contact with one another and causing some interference perhaps?

FWIW you seem to be having more issues than I am so far, although I have some issues too and things I want to follow up on.

iGo app won't save settings. I've looked around and some suggest creating the (missing) "save" folder in the iGo path on the provided SD card or making sure folders aren't read-only. I haven't experimented enough to be sure but those options don't appear to be solving things for me.

Can't remap the "modes" to other apps. You can set the navigation app so that its Google Maps instead of the default iGo (which I'll probably keep if I can't get iGo working consistently) but you can't seem to do this for the Radio and Music apps. The Radio app I can live with but the Music app is not somethign I want to be stuck with

There seems to be a reduced amount of widgets available for any given apps that would otherwise be visible on a proper phone. Changing the launcher may reveal others though. (e.g. no Subsonic widget on the provided launcher but one does show up on alternative launcher). Suspect this is a common complaint for these units and not specific to this model

Haven't tested this enough yet but when making calls to my wife she was getting an echo on her end. Otherwise she said my voice was clear and she sounded clear enouhg

Google Maps navigation voice stutters and breaks up. I think I've seen this referenced in another thread about what Manufacturers could do to improve these products so that sounds possibly more universal.

No way to manage the fast boot functionality (afaict). So far I'm loving how fast it turns on but I do wonder if I take trips and leave the car in my driveway for too long if I won't come back to a dead battery. I've seen mention of factory settings passwords that will reboot and possibly shutdown the HU but haven't tested them. That would be a good enough compromise for the need.

SWC app does not work Not sure what i'd change but would like the option to.

Otherwise really enjoying this unit so far. Need to figure out how to start and stop my hotspot when my phone has paired to the HU over BT. Solutions I've seen so far don't seem to work, not sure if that's because I'm using a Nexus 6P on Nougat or not. (tried solutions being free version of Hot Spot Starter and AutoTether)
