[Android Head-Units] tobias.s:
Installed it, but it does not update the MCU. The MCU update is different from Android itself. Mid last year there was a second file package on the Cusp Website. It was the software for the MCU (March version). They took it off. In addition to that, they changed a little bit the layout of the PCB with a change of the MCU.

Here are some picture of the interior of the unit that I found on the Web, may be it could be handy for someone:

There are some really ambitioned Russian guys, who are trying to "reverse engineer" the unit to make it here and there better.

I am now stuck on 20130906. It is okay, sometimes I get little connection problems to my mobile Wifi router. I don't use Bluetooth of the unit because it is too buggy + extremely loud compared to android media. The same for the FM-Radio, I switched to streaming Radio cause it has a much better sound and it simply works even with the steering wheel control. For navigation I use Igo, pretty stable on the unit. Google Maps works only for a while (10-15mins) then it crashes or reboots the whole unit. I am using it only for some min's to see the traffic of the surrounding roads. I don't know if some specialist here can find out the cause of the crash. I logged it with catlog, here is the part of the crash:

After that, maps can't be started anymore.

Btw. please take a look at the mouse cursor in the attached picture. Does anyone have an idea which app or system service brings this one on the screen. When I start maps it is always there and when the whole unit crashes the mouse keeps its place on a black background.
