PUMPKIN CAR STEREO SUPPORT CENTER

Hello,
I have purchased a Pumpkin 2GB RAM Android 5.1 Car Radio Stereo 7-Inch from Amazon.co.uk (https://www.amazon.co.uk/dp/B01N2G2A6P/ ... 71_TE_item)
Order #205-1681482-3276351
Placed on April 17, 2017
It has been installed by professional
I read that the stereo should do a fast boot but in my case every time I switch off the car it has to boot and it is particularly annoying when you are using the navigator and you have to search anew the destination
And also the stereo start always, even if I switch it off before switching off the car it it always start. I would prefer that I start the stereo by pressing the button myself only when I like to.
In your experience what is wrong with the wiring?
There is a updated rom for my stereo?
Thank you Mauro
