Steve-
I've searched up and down XMfan, Prius boards, Lexus boards, Toyota boards and haven't found anyone that has used the LS/Solara/Prius kit in the ES and reported on it.
My Lexus dealer will sell me the LS kit ($500) but won't attempt to install it. They tell me it won't work. When asked about the Solara kit, the Lexus cust. service dept. (800#) says they are not familiar with Toyota products. Toyota dealer says unfamiliar with Lexus products
Please don't take offense, because you are a much appreciated resource and a terrific help but how did you come by the info you have because I can't find it anywhere?
I'd like to at least confirm someone has successfully added the kit before I jump in.
Thanks,
Jeff
