I do a lot of highway driving. It'll frequently tell me "in X miles take the exit towards [whatever]" but it will refuse to tell me what exit number I'm looking for until I'm within a mile or two of it. This is frequently a problem when I have exits with A/B/C branches which is often. I don't give a shit if I'm exiting towards I40, just tell me I'm exiting on 13B, and tell me that from the beginning.

It used to do this, it changed a couple years ago, and I've been pissed off about it every time I've had to drive somewhere since then.

It'll also randomly change voices on me, it'll flip flop constantly between the American accent and a thick British accent. No rhyme or reason to it either, it'll be a different voice on the same turn on a different day. Drives me nuts.
