Hello All,

Would like to purchase one of these items everyone has been discussing and required for my handhled Garmin GPS. Most important question will the audio directions from the GPS over ride current play source, then resume? Much like the integrated cell phone mutes music while on a call. I have installed the Costar device I learned about here and very happy with it, now I look to you all to help with this question.

Also please feel free to comment with other pros/cons about these two devices, or other suggested items available.

Regards, CCI_TBLT
