AVIC-Z150BH I bought this unit and installed it late last fall so didn't get a chance to test it out with the top down. I'm really disapointed in the brightness of the display. In map mode with the top down I can't hardly see the display at all. I have the brightness and contrast turned all the way up and makes no difference. I have a Garmin gps on my motorcycle and a Garmin gps for the car that is way brighter than this unit is. Even in the music mode screen I can barely see it unless I put the top up. Had I known this would be so dim I wouldn't have bought it. Oh well, it is what it is. Stil
