I know you've stated that you're reworking the pop-up bubbles that notify the user about the upcoming intersection, but I just wanted to mention this to make sure it was being considered. There are some roads that have different names depending on which side of the intersection you are on and the notification bubble only mentions one of the road names. Here's an example:
Cty V77 (Gilmer Road) on one side of Mundelein Rd, and Oakwood Rd on the other:

Driving South on Mundelein Rd, the client identifies the intersecting road as only "Cty V77", even though it is also intersecting with Oakwood and that might be the street I am looking for.
