Great Product03/18/2016 ByFulio After buying my radio from another retailer, I was told I had to install the horrible XM aftermarket antenna, even though my car had a standard radio with satellite. After doing some research, I found your website and your help was crucial to make sure I could use the existing hardware in my vehicle. Not only this product works great, your customer service is second to none, even for such a small purchase as mine. Thanks again. Great product, great service and I will certainly buy from you in the future.
