I had a GROM in mine until I swapped out the stereo. To get the echo down you have to wire it to the overhead. The wire that comes with the mic is long enough to go up the DS A-pillar and across under the headliner. Just make sure you go behind the airbag and don't mess with it too much. 2 bolts to remove the grip and you are good to go. My Alpine system was a needed upgrade for mine since all the speakers were blown and the head unit has everything, including the ipad mini charging USB port and BT for phone, streaming, etc.
