08 e4 - tablet holder and seat covers

anyone know a good tablet holder that can be mounted to chassis somewhere in the middle dashboard area for a 2008 e4? ive seen some golf carts with a nice screen mounted on the dash that has a visor along the top and sides of it and it looked pretty rugged. ideally i cna leave the tablet in the gem car full time.

also, anyone know which seat covers would fit ?
