Hi,
I've got some problem with my HFS and my phone...sometimes it forgets my phone and I have to re-syncronize it. I remember a TSB somewhere and the solution was to change the HFS module.
Long story short, the dealership (amazing one) call me the other day and today I brought the car in for change it... no way to make it work.
The new module was able to send bluetooth signal but, after having done the normal registration process (when you have to assign the code by voice) my phone and others were "unable to connect to hands free system".
With the old one, after doing the same thing we had to type in (on the phone) the code to pair it with the car and it was as easy as that.
Now my Evo is a 09 MR and there is some reason why (exept a faulty module) it can't work? I've tryed playng with MUTIII but I've not seen any process related to the HFS module initialization.



From the picture can you tell if there is something wrong (code-other)?

Thanks
