I put my Jazzy aux-in in last week and it works well with my Garmin 2820 and Ipod routed into it via a Cleansweep CL-SES. I'm looking at putting the Empeg in the glvoe box to keep the cubby near stock. Volumes are a little low compared with the radio or normal CD operations but sounds good, at least to my untrained ear.

BTW, watch the screws on the side that connect the ground wire and the brackets when disassembling. I wound up stripping one as did another person recently.
