Anyone out there upgraded the steering wheel switches on a 2005 XLE to 2006 XLE Limited style with the phone/talk buttons on the right side of the steering wheel? I am hoping to do this as part of an audio head unit upgrade. Looking to use a PAC steering control adapter or I-Data Maestro RR to integrate the steering controls and the JBL system etc. Please let me know if you have done anything similar to what I am contemplating. Thanks in advance.
