Thanks taqu and mmmbop re POI and logging.
tabs - from what I've read, the main difference btwn PPG Pro and Lite is that Pro has the Junction View feature.
I've only been using PPG for about a week but I must say JV is quite helpful.
Given that at times, PPG (more a function of iPhone GPS engine I suppose) may 'lag' a little and plot your position a bit late - having JV can help you not miss your turning by providing a visual clue as to where you should go, as it comes up a fair distance before the junction arrives.
I have the same annoying issue as iori57, but again, think this has more to do with the GPS engine in the iPhone - although, a better (?) algorithm in PPG may be more 'intelligent' not to 'jump off the road' so quickly, e.g. by assuming the car hasn't suddenly lept 200m to one side?
BTW, I have yet to hear any audio instructions from my PPG! It does not bother me too much as I don't rely on audio but am wondering all the same what gives!

April 23rd, 2010 at 10:43 AM - News by Jeff Gamet
Google is bringing its own turn-by-turn navigation to the iPhone, and it won’t be charging for the feature. The Internet search giant hasn’t said when it plans to roll out its new navigation features for the iPhone, but did confirm that it’s also rolling them into its Google Maps app on the Android platform, according to MacUser.
Unlike some turn-by-turn GPS navigation apps for the iPhone that include their own built-in map sets, Google’s system will rely on an Internet connection to build and map routes to locations. Google will, however, cache the maps for a route ahead of time assuming users have an Internet connection when they enter their destination.
“Google Maps pre-caches the entire route. It needs a data connection when you ask for navigation. But while driving to your destination, if you intermittently lose the connection, it will still carry on. As long as you stay on the route,” explained Google’s Mobile Maps product manager, Steve Lee.
Google’s plans may be good news for iPhone owners that can’t afford other turn-by-turn navigation apps, but companies that already offer similar products through Apple’s App Store will no doubt be watching closely to see what impact Google’s route into their territory has.
