I have changed the light color in the hang up/speech buttons from bluetooth system to make them similar to found in the cell phone, and I'm very happy with the result obtained. I used common LEDs. Here one pic

 

That looks really cool...

 

that's awesome...

care to do a write up/step by step instructions?

 

Holy crap jsrd!!!!

That is sweet. Nice work.

How easy do the buttons pop off to replace the led?

 

It´s easy:

1. With your fingers remove the back cover (item # 3 on diagram)
2. Remove two screws that fitted the buttons module to the plate on steering wheel
3. Unpluged the connector
4. To di-assembled the module, to remove some screws (I don´t remember how many)
5. Unweld the OEM LEDs
6. To weld your news LEDs.
7. Assembly and reinstall following the sequence in reverse order




Good luck

 

That's awesome! I'm putting this on my to-do list!
