Leaf Spy has nothing to do w/the nav system. It dosen't matter if you have nav or not. Leaf Spy doesn't use it. Having nav doesn't help. Not having it doesn't hurt.
For Android, start with viewtopic.php?f=44&t=14284
and compatible dongles like http://www.electricvehiclewiki.com/?tit ... th_Scanner
For iOS, see viewtopic.php?f=44&t=19147
. I don't believe there's a free lite version. The developer (Turbo3) seems to recommend LELink (viewtopic.php?f=44&t=19147&p=473679&hilit=lelink#p473679
I use the Android version but I carry both an Android phone (Google Nexus 5X for work) and an iPhone 6 (my primary personal phone).
BTW, although not related to getting Leaf Spy setup and nav, xan you update your location info via your user name in the upper right > User Control Panel > Profile tab? That way, we don't need to ask in future posts/threads or do sleuthing to deduce it. It may be relevant for future questions/discussion.
But, from YVR, I'm guessing you're in/around Vancouver BC.
