The Vehicle Sound and Alerting System is generally comprised of a conventional automobile stereo system that has police radar detection capabilities. When police radar is detected, the stereo's volume is immediately muted. An audible alert is then outputted through the vehicle's speaker system or a built-in speaker on the control panel, or a combination of both, depending on how the driver has it configured. A visual alert is also produced on the control panel, which displays the band of radar that was encountered, and its relative signal strength. The radar detector receives signals from the vehicle's antenna and an auxiliary antenna. The auxiliary antenna is attached to the vehicle's grille. This improves the signal reception ability. The present invention eliminates many drawbacks associated with conventional radar detector units, such as their obviousness which has tendency to attract thieves and vandals if left unattended; their inconstant effectiveness caused by impeded reception ability when they are mounted improperly; their bulkiness; and potential to produce visual impairment and distraction.
