ublox neo-6m

I received yesterday the ublox neo-6m GPS module for my arduino. hooked it up downloaded the TinyGPS++ library and run som tests as you can see in the attached file it took some time until I received satelite data. I placed the GPS in the front window of my car. I got 2 issues with the reading first is regarding the number of satelites first it showed only 3 and after a couple of minutes none but Lat and Long was received ok. The second issue is with the altitude I got no reading for that. The code I used is the basic code from the library only chaged the GPS baud rate to 9600 as the neo should have this baud rate.

Anybody had similar issues?

With 3 satellites, the GPS receiver can only determine your 2D position: lat/long. You will need 4 satellites to determine your 3D position: lat,long and altitude. With good reception, you should be able to receive 9 or more satellites.

Perhaps the surrounding buildings are blocking reception?
