Ok here is the review of unit. I have extensively used it for 3 days now.
First of all to my surprise 1gb ram is more than enough.
I mean i regularly used google maps on it and it ran so smoothly even better than my 4gb ram phone, i dont know how.
Used youtube on it with no lag at all. Installed car launcher, sound cloud etc. Everything is perfect and runs very smoothly. I have no issued at all with its operation and touch. Touch is very responsive.
Now coming to negative points, all the controls on left don't light up in night. So it is very difficult for me to control volume etc cz of lights not working.
Checked with electrician and he said it comes with grip to grip and upon my insisting he throughly examined it but lights are damged may b.
2ndly viewing angle from driving side is not good.
I mean you can look at the screen from any angle in whole car it will look same and bright but only on driving seat it becomes very dark and when u come in front of it, it becomes clear.
