Putting in a BT OBD unit with an adapter cable to locate it out of the way.
Will use the Nexus 7 for gauges, GPS (tethered to phone), V1 integration, media (Pandora, SiriusXM, TuneIn Radio and iHeart).
The mounting will cost about $40, the tablet $200, the apps less than $30 and the BT OBD reader less than $40.
You might want to try the BT OBD reader with your phone first before you spend the rest of the money.
BMW doesn't use any (maybe few for emissions checks) of the standard OBD PIDs so none of the information the standard OBD apps display is accurate and if you have a Procede or JB4 those fake the important readings so you have to connect directly to them to get the correct data.
