I have a 2013 accord lx. I am wondering if there is a XM radio adapter than can be plugged directly into my head unit so I can control the XM from my head unit. If not, does anyone know of a good aftermarket XM radio system?

 

depends on what you got now. if the stock radio you have has an XM button already,along with the antenna already installed, and you just need to activate service and maybe install the receiver (between HU and antenna) - then adding it to factory is doable.

if you don't have the antenna and/or XM button already - then aftermarket is your best bet.

XM has merged with Sirius, so anything new will work. It's just a matter of choosing your preferred cosmetics and features.

getting audio to your head unit is the next challenge. if yours has an AUX input, then simply use a stereo cable from the aftermarket XM unit to the AUX input. if it does not, then you are needing to buy an adapter (from PAC-Audio or GROM Audio or USA Spec) that adds an AUX input (also useful for portable players and phones).
