I had my 2006 LR3 HSE fully detailed yesterday. (Not the engine compartment) The carpets were shampooed. The detailer told me to leave the windows down for a few days so the carpets would fully dry. The entire floor of the Rover is really damp now. I live in an apt. so leaving the windows down is not an option unless I am driving.

The drive home from the detailer was fine. The next day (Today) I start the car and the there is a popping/crackling noise randomly coming out of all speakers. Even if the radio is off it will randomly make these noises.
Driving or parked it does it and even with the engine off.

Here's how it goes.
I turn the radio on, My Bluetooth iphone connects as usual. At some point, the speakers will make this popping sound and the audio (am/fm/aux or whatever) will mute until it decides to pop again. The audio will resume playing from the speakers. Some times when this occurs, the radio will display "Phone Connected" even though it's been connected.

My guess is that when they were shampooing the carpet, they over soaked it and moisture got into or onto some electrical connection. I have the Harmon Kardon Logic 7 system. I checked the amp under the passengers seat. It looked and felt dry. I checked the connections on the back of it and they seemed dry and fine.

Any ideas ?

Thx,
Lenny
