Here is a nice hack i found, i was just crying because my car wouldn't read my text message while on drive mode. after researching, heres what i picked up. There is a operation restriction function that can be turnt off allowing the # dail and navi address search to function while in drive mode. Along with the text/email.
To access the operation restriction tab you must enter the diagnostic settings
For the premium models (2 screens without navi) hold the back-audio-menu buttons for 3 sec until this screen appears
On this screen now hold the enter botton for 3 sec and u should end up in the " for developer " screen, as so...
Scroll down the operation restriction and hit enter and on this next screen hit OFF like so...
Now select return and continue selecting return untill you are back out the diagnostic menu.
All restrictions should be off and you should now be able to search a address on the navi and view your incoming messages under email.
For those of you with the tech plus it can be done as well just have to figure out which bottons to hold that leds the diagnostics menu you should try navi-menu back bottons to see if that works
Note. You will need to perform this process after the car is turnt off, for it will reset back to restriction on, i do it when I'm warming up the car, it doesn't take long once you know where to go.
On that note please be safe while driving .
