I have befriended the most knowledgable tech at my local ford dealership, who knows (he says) quite a bit about how the ford central hub/computer works.
Anything is possible he says, however, the difficulty is Ford does not tell the dealerships how to do any modifications. AT ALL.
Here's what we can do, and with some research, we may be able to get some of what we want, quite easily and cheaply, since its all computerized...
I want to enable the external temp display and the compass to start with. Eventually I would also like to upgrade my instrument panel so it has the message centre also.
To do this, next time you are at your dealership service department, request a print out of your vehicle VIN "AS BUILT REQUEST".
This will be a 4 page print out of all the codes that make your vehicle computer do everything, including what sensors are built in and what sensors to expect (and then report if they are not working), what radio you have, what display console options there are (including the temp/compass), whether you have Sync or the NAV package, engine size and options, a/c system (auto or manual) etc etc.
The important part is the BCE modules, which are 4 digit HEX codes. The dealer can change these hex codes manually. The problem is, they dont know what the codes are for, or what to change them to, Ford will not tell them.
SO. I walked around the lot and finally found an identical Escape to mine - except it has the TEMP/COMPASS display working. AND it doesnt have any different buttons anywhere. Its basically identical except for the temp/compass and the instrument panel that I want with the message centre.
I asked (and received) the AS BUILT REQUEST print outs for both my 2010 Escape XLT with sync, and the dealerships service taxi 2010 Escape XLT with sync and the other stuff i want.
I'm going to add the temperature sensor in the front bumper, then go to the dealership and ask the tech I have befriended to change a few HEX codes from what I have currently in my truck to the HEX codes in the other truck - and see if the display starts working.
I will scan and email the AS BUILT REQUEST forms to anyone who wants them, or even better, we should start a new form that says what codes are for what function when we find them out. We should be able to discern what some of them are by comparing the HEX codes to the features each of our trucks have.

I have a 2011 Base Mariner 4 Cylinder and found the temp sensor (or where it is supposed to be screwed on) under the bumber. It has a plastic gray cap that has threads and a sharp looking point on the end. I am going to order the temp. sens from Ford and try putting it on to see what happens.
