Micnova GPS-N on Nikon D7200. It is not starting even if correctly connected to camera and "On". Camera is "On" too.

those lenses are usually manufactured for specific model cameras if it works fine on your it's because that's the type of camera it was manufactured for. if it doesn't work on hers in AF then it's because the pin out on the lense isn't the same for her camera as it is for yours.

yes, it is compatible.

By not clear do you mean out of focus or streaked due to movement? Try using a higher ISO setting in order to allow for a faster shutter speed and/or use a tripod.

The Smartphone connects to the camera NOT the camera connects to smartphone. You have to have the APP on the camera. You first have to turn on WIFI ON the camera. It is like a server. Then you turn on WIFI on the Phone and connect to the Camera WIFI.

Did you switch on the GPS outside? because as long as you are in a building, the GPS won't receive anything from any satellite. Whe outside, give the GPS at least 2 minutes to find any satellite. Being outside, but between high buildings will have the same effect as being inside.

Did you instal the software that came with your camera?
You also can download the new View NX from Nikon for free. Always first install the software, before connecting any device on your computer. Special what it is a device like a camera.
The computer can interpret a camera on an USB for: Now I nave to charge the battery. Or when you start the program to transfer pictures, now I have to download pictures, or some camera's like your D200, also cam be controlled remotely over the USB, if the correct software for that is installed.
The software windows needs to install has to be on the computer first.

The D-90 does not come with an internal GPS. However, one can be connected. If you have connected a GPS and are getting this error message, I would suggest you contact both Nikon at www.nikon.com and the GPS manufacturer to get help in troubleshooting the problem.
