I've used info plus a fair bit. Much better than trying to enter post codes etc while driving....
However major fail at weekend, low pressure warning came on, phone info plus because I wanted to get hold of BMW roadside assistance, they told me to press the red button in roof, which dails 999

So then tried the "Mobile Care" option which is roadside assitance i found out, they suggested to go to dealer but they couldn't send directions to car, so back to info plus who try to direct me to a delaer in manchester claming I was only 5 miles from them, even though I was on the M6 just north of birmingham and was therefore many miles over the 50 miles you can drive on run flats

then despite telling were I actually was and that I wanted to go to dealer on the way north rather than turning around, they finally send me direction back to birmingham. So gave up put some air in the tyre reset the monitor and booked it in at my local dealer for when I got back. Got away with that.
It's worth pointing out the initial 3 year subscription include roadside assistance which is over £100 from the AA if this is included in the £120 a year from BMW on renewal and isn't another extra then it's got to be worth it.....
