qwik does have "Lane Assist" for the description of the different junction view files in the first post. Not sure if he got that from Garmin but technically smokefree is correct. JCV has nothing to do with the "Lane Assist" function. They are 2 totally different functions. These files should have descriptive labels such as "Junction View Full" and so on to avoid confusion.
On another note with all these files qwik can dig up from Garmin it would be great if he could get a PNX file used for the Kenwood/Garmin units. Name for 2012.30 would be 01YWSTTS.PNX. Same name as the SRX file for the ASR files but a different suffix. Or it could be 01YWSU0W.PNX to go with the other set af ASR files as the kenwood unit came with 3 separate ASR files and 1 SRX file and the matching PNX file.
