I installed the F700BT in early April and have been running the cmh928 hack/mod. It, for me, is the best of the bunch and importantly the easiest to install. There are others that use specialized launchers and that completely redo the nav OS. Haven't ventured into that yet.
Not the best pics ever.... and I think the latest update is even better than these.
Anyway to do the hack you need an SD card unformatted.
Copy the files from his site, I'll have to find the link.
Un-zip the file downloaded and copy the testmode and MiTaCAP to the root of the SD drive.
On you headunit, with everything shut off, insert the SD card and start the car/power the unit up.
It will take awhile and it will show copying files. Once it's done there will be a green rectangle on the screen. In the far upper corner there will be a 'x' use the stylus or something to click that 'x'.
Turn off the car and remove the SD card.
Power up the car..
It will take a little longer to start up the first time as it's copying everything over.
Caveats
1) Read up on the site on how to backup your system
2) Get a 4GB minimum SD card. Backing up mine was 1.8GB and I have a 2Gb card, I was lucky to be able to back mine up.
Hope that helps.
Should also mention that there is apparently a new version of the firmware that's due out, 3.0, and it might lock down the unit from hacking. Don't know how true that is but it's probably something you should watch out for.
