hi LineitUp, any updates?
I'm working on something similar as well. I have bought a new Fascia and AC control kit from Amazon. Have a double din kit on its way from ebay.
The idea is to use the lower half for the 2din kit and replace the pop-up screen with a 7" tab. However, after measuring up the casing for the pop-up fittings, i'm finding it difficult to find a tab that would be good.
Also, how do you plan to have the OBD data displayed on the tab? Coz, my v35 is does not work with any OBD protocols at all. The connector is OBD, but apps like torque keep saying that they can't connect.
Any ideas/ suggetions would be appreciated.
