Hi,
I am trying to figure out how to read the position files from Navigon for the IPhone. Even though they called .targets it does not appear to be the same format as the .route format as suggested by this commit:
https://github.com/cpesch/RouteConverter...30f64876e1
By that I mean that renaming the file and opening it as a .route file doesn't work.
Just opening the file in a hex or test editor, it definitely looks like a binary format (readable string snippets sprinkled throughout the "noise"). Can you tell I am not experienced with binary formats?
The reason I want to open this file and convert it is because Navigon have sloppy QA. Apparently I shouldn't have expected my stored favorites and routes to survive a software update. So, I extracted the iPhone backup on my computer to gain access to the files. Since I am apparently not alone in loosing all my data it may even be a useful feature for RouteConverter.
What I was hoping for was simply some basic tips on how I might try to parse this file. I am a web-developer (= happy to write my own scripts and do some unpack on the data in various ways) but I rarely and reluctantly deal with binary files of this kind.
Any ideas greatly appreciated
