With enough money and time you can do anything. The radio connections for the LX and EX models are NOT directly interchangeable. There is a member who did it, but wasn't a job for the unitiated. suggest you just use an XM adapter for that. The LX is a analog heater control, the EX digital.All,
I tried searching this through the forum but is it possible to install the XM/Dual Zone radio into an LX and with the purchase of the XM antenna, still use the steering wheel audio controls or is the only option an aftermarket radio ?
