I have a 2004 TL and recently my cd changer started acting up and wouldn't eject CD's, eventually that led to my entire stereo going down (the whole thing would just shut down, unless I kill the engine and restart).

So I picked up a new one off eBay. I got the unit yesterday and installed it, and everything works fine, EXCEPT for the HFL!

When I press the HFL button on the steering wheel. The LCD changes and shows that HFL mode is active, but the music does NOT stop playing, and I cannot hear the voice prompts or anything. When I give it voice commands it seems to follow them (I can see the LCD changes), but I get no audio response.

Does anyone know if the stock OEM radio/cd changer has to be a specific model with this capability, or rather if all of them have this capability, but maybe this unit is defective for that feature?

The original one says the part number is 39100-SEP-A000 but the new one says 39100-SEP-A011.

If anyone can let me know, I'd appreciate it. Thanks.
