I never had any problems with the steering wheel audio control. For my 96 RL (base model) the part is 35880-SP0-003; list is 91.73; acuraoemparts.com has it for 73.38. It fits 96 - 98. I have the part if anyone needs one. (I parted out the RL).
hnic - what is the problem with the speakers? The stereo in my RL always seemed underpowered, but there were no real problems with it.
RaiC - the flaking "chrome" on the door handle is common in older RLs. RLs in the US have the CD changer in the trunk; while in other countries, it is in the console.
I'll have to check my stereo and speakers when I get home. I thought it was Bose...
