wont the futaba 3003 work. its cheap and works good. my friend has that one with his stock radio system.
The Futaba 3003 is about $15 and is better (probably) than what came stock, but you get what you PAY for.
The one Ehroof listed is about 2 levels better than the Futaba 3003. It will work better n last longer.
