Hello everyone! I am looking to change out my factory receiver for an In-Dash GPS/Stereo. I have been looking at reviews for Pioneer, JVC, Alpine, and Kenwood, but wanted to get your actual feedback. I would be looking at one of the higher end models, and an example would be:

Kenwood Excelon DNX9980 HD
Alpine INA-W910
Pioneer AVIC-Z130BT

Any advice, or feedback?
