This is where the OEM navi system shines! When the nav system loses a signal from the satellites, it relys on the data that it receives from the compass and the speed sensing system in the car to "project" where your car is until it can re-gain a satellite signal. This is how your navi system works in tunnels, in cities, etc. Show me an aftermarket that does this!like_the_altima wrote:Dumb question, but how well does Nav work in cities and in NYC in particualr ? I am talking specifically about reception around tall buildings in cities, as well as knowledge of one way streets.
(I have the nav in the 2008 coupe, not sure exactly what version though)
So that's why i still get it when I go through the Lincoln tunnelmarlin29311 wrote:This is where the OEM navi system shines!

Yup! It took me a while to find this out too - first time I thought about it was when i went through the tunnel on 95 through baltimore - i was like, how does it know where i am if im under the river....dangeris wrote:

LOl... how many times do I have to debunk your myths about the factory Navi system???marlin29311 wrote:

And o yea - I've used the navi in NYC a bunch of times without any issues ever (traffic cops over Christmas not included).

Pioneer's systems tap into the speed sensor wire for just this reason. It uses a combination of the GPS, the speed sensor wire, and the built in internal gyro sensor to establish where you are and far you've driven when you lose connection with the satellite!
Oh yeah, and they have the 1000 other things that make them better than the factory navigation system! Nice try Marlin, but no dice on the factory Navi being anywhere near better than the top aftermarket Navi systems out there
Oh yeah, and let's not even talk about the WAAS (Wide area augmentation system) used by kenwood in their Garmin powered navi systems that use both satellites and ground stations across North America to provide for continuous location corrections as accurate as 3 meters! This technology is now being adopted by the Federal Aviation Administration to make flight approaches more accurate. Garmin set the standard for EVERYONE when it comes to navigation accuracy!

Haha, j/k - i was unaware that the pioneer system did integrate into the car systems...my bad there. But OEM integration FTW still. Either way, the OP already has a navi system, so it's pointless to debate which is better at this point.
