Well, I downloaded navigon and got the traffic expansion and I have to say I'm unimpressed.I have a normal route I travel to work everyday. I can go back roads or over the highway. The highway is 1-2 minutes shorter if there is NO traffic. Navigon wanted to direct me onto the highway even though I could see from the overpass the highway was at a standstill for at least a mile and google maps showed it at a standstill for 5 miles. It would have taken me an additional 20-30 minutes via the highway but that was the direction Navigon wanted to send me. It has done that everyday (as that road almost always is congested in the mornings).
I also own co-pilot and it is missing all kinds of addresses so I don't use it.
Ugh, I'm loathe to say I still use the TomTom app because it always has the addresses and the best routes. I hate the way it handles audio by stopping the music from my ipod. The new street name voice audio only happens on the final notification as you are just about to turn on the street instead of a mile down the road (need way more heads up). The new ipod controls don't let you control playlists or songs, it is simply the same controls you get when you double tap the home button.
Man, when is someone going to combine the good elements. Also, what is the freakin difficulty for these companies to give me a downloadable manual that explains the difference between "optimal" and "fast" routes or how live traffic makes decisions on when to reroute? I mean seriously, a $35- $100 app with no manual? We have facebook support? Really? Only 24 hours to answer my question that explains what should have been in a simple manual? Awesome. How have these become international companies?
