That was among the first generations of iDrive. I was (and to some extent still am) skeptical, particularly given how overwhelmingly negative the reception was at the time. But, FWIW, the motoring press was later – as BMW apparently improved the system significantly – swayed to accept, and sometimes even praise, the iDrive. At least from about 2015-20, or possibly as early as 2010-15.
Can't give any personal evaluation, as I've never (AFAICR) driven a BMW.
