Very good antenna, it allows our devices to obtain a solid GPS lock very quickly (within 10 seconds usually) instead of the 15+ minutes we had waited with the previous antenna

My phone also had terrible GPS reception in this particular vehicle, so I don't think it was really the GPS antenna that came with the car stereo.

and it came with a GPS antenna, but in my SUV I was getting really poor GPS reception.

Works as well as our $900 gps we use in commercial applications.

This Gps antenna works just as good as the one that came with the guidance system on my spray rig
