The MCU I used is
KGL v.2.55 with sleep and redesigned sound processor from darkleo - MCU_KGL_2.55_Sleep_Musik.rar
and the Rom I also picked JY, the top one in the list of 4. Rooted but it turns out, like you say, it does not have the sleep timer function. I was looking forward to that feature so I may try a couple of the other ones considering how surprisingly easy it was to flash.
Good shout with the Nova launcher! Very good customisation. I can control pretty much every aspect of the dash. I love it! The only ting I have noticed.... when using Nova, the reverse camera video is not as smooth. Real jerky, like a its lost about 10 frames per second.
I'm not sure about TomTom, is it worth the hassle? I was reading a thread where people were having problems and I'm not even sure what side loading is although I've seen it mentioned a few times.
Think I'll stick with iGo for offline as it has never let me down and Google Maps for when the very temperamental 3G Dongle decides to work.
Also I found out how to get the head unit lights on with engine start instead of the headlights if your interested. Go to factory settings (passcode 126) then just tick a box labelled 'key light' then press apply.
Also my open door graphic was mixed up. It would show the left door been open when it was actually the right door and vice versa.
In the same menu just tick a box called 'rudder' and apply. Fixed!
