The big red circle suggests that there are four buttons, or tactile senses. But this is not so, or I'm too dimwitted. The receiver can be turned on and then wait for a Bluetooth device (in my case an iPad and / or iPhone 4).
The pairing is easy, activate Bluetooth and wait. If the device is found, takes place immediately connect.
Only way the functionality is really to check on the left in the AppStore program. This gives quite liberally award all possible data from the GPS Receiver. Whether the receiver now works among the programs on the iPad and / or iPhone, you can not figure out. It is not signaled.
I was hoping that there is a possibility that adjust the iPad, but this is not so. So you have to rely on and has somehow always feel to have a big red button in the car, who does something, but not in conjunction with the navigation program.
If you switch the tracking on the iPad / iPhone out, unfortunately also works the GPS receiver is no longer, as it seems then probably a problem in the interface to give. It would be desirable if the programmers would consider such a thing. Which must be clearly borne in mind that it is hardly a problem of GPS module.
For Windows 7 on a notebook unfortunately I could not connect to the GPS module, is probably the but ehr to Windows. While it is recognized as such by common navigation programs under Windows but not found.
As I said, may well be due to me. I wanted to have the module for the iPad, as I always have been there again in conjunction with Navigon GPS signal, but what can I fix the built-in A-GPS iPad. An extensive test while driving will show whether it has changed something ...
ADDENDUM: The GPS module is not currently recognized by the iPhone 5, state of affairs on September 27 ...
