A small follow up on Herbert's post about fitting a Dynavin into an E60. I recently had one installed into my 2005 Japanese spec 525i. It took the installers 7 hours to complete it and then I was left with the airbag light lit, it needs to go and get reset if I can find the time.
Comments on the Dynavin system? It works ok, the navigation is a bit slow to update and it doesn't always find the best route, I tried it going from work in KL to my home and it did not want to go the way I always go, it is quite accurate on my location though.
One major gripe is the IDrive controller and the reaction of the Dynavin unit to it, when I move the controller to operate the function or settings of the Dynavin system it is far too sensitive, for example to move from one function to the next in the old system was just a click of the controller, now when I move the controller the function on the Dynavin system jumps around all over the screen, I am told that Dynavin is working on a fix and that the problem is caused by the Jap spec controller.
The rest of the functions seem to be working ok. If you are considering installing into a Japanese spec car PM me and I will give you more information.
UPDATE
The car has been back to Dynavin and they tell me that because my car is a Japanese spec then the system will have issues when using the idrive controller. very frustrating, if I had known this I may of considered replacing the complete computer and not just the head unit.
