So I bought this unit: UPDATE (6/6/2010): BTSTACK GPS version 1.3 WORKS WITH NAVIGON ON iPAD WIFI (non-3G model)!!!! AND it fixes the JUMPY speedo! so it's all good! Video of working Navigon + iPad Wifi model + BTStack GPS 1.2-24995 + QStarz Q818x: http://www.youtube.com/watch?v=2yU6raDM3TY You can fast foward but there are some speed issues (the MPH indicator will go bezerk but the GPS data is accurately maintained, however. Email is dispatched to the dev regarding this issue) QStarz 818x Bluetooth 66Channel, MTK2 external GPS unit w/A-GPS what it comes with: the QStarz 818x unit USB Port for charging (AND DATA!): The Control switches (1-5Hz for API software tracking): The bottom of the unit (includes anti slip; gripping pad to put on car dash or texture surfaces): The lithium-ion battery - good for 42+ hours CONTINUOUS USAGE! The size of the 818x compared to an iPhone 3GS: The Thickness of the 818x compared to an iphone 3GS with case The unit in pairing mode (yellow and blue lights; battery green light to the right of the bluetooth) I am using roqyBT (GPS) - on the iPad - Video of satellite sync http://www.youtube.com/watch?v=yIIX1Y0iW8w (see post #61 for details) Video of Navigon running on iPad WIFI model using roqyGPS w/QStarz Q818x GPS unit. http://www.youtube.com/watch?v=xCLTxZIXMFY (see post #62 for details) edit: 5/10/2010: Navigon seems to have a problem on the iPad - I'm sure it's a navigon only issue since google maps has no issue whatsoever using the roqyGPS and my QStarz Q818x unit. Google maps actually track movement without problems...just that there are no maps being update as the car moves obviously since it's not connected to any data. in theory, this should work 100% I will know when my gps device arrives. 1) Install roqyBT 2) Use bluetooth GPS device 3) Use Navigon software (even if not iPad compatible yet will work) edit: 5/11/2010: Navigon DOES INDEED TRACK - HOWEVER IT WORKS WITH QUIRKS. WHEN YOU ARE IN THE "SHOW MAPS" MODE, YOU WILL SEE THAT NAVIGON DOES INDEED TRACK YOUR POSITION. WHEN YOU TRAVERSE, IT WILL DISPLAY YOUR COORDINATES IN REAL TIME. HOWEVER, IT HAS ALOT OF ISSUES SUCH AS ORIENTATION PROBLEMS (SHOWS THAT YOU ARE POINTING IN THE OPPOSITE DIRECTION BUT MOVING FORWARD - GIVING A LOOK AS IF YOU ARE MOVING BACKWARDS!). When you set a destination to go towards, it will pinpoint your current location - then it just stops and not update your location; it seems that way but during your traversing, navigon will sometimes randomly display your movement but at many times more than some, it will show you moving strangely! But GOOGLE MAPS WORKS!! (see post #69) http://www.youtube.com/watch?v=7FB8GVzA5nE You don't even need to have the iPad 3G model to get GPS! Thanks to roqyBT, you can use almost all NMEA GPS receivers! I'll report back when I get the gps unit this week!
