I have a brand new ram 2500 and I brought it to the Ryan and the guys at LA Stereo. Being a brand new truck, it had all the bells and whistles. However, when they installed my in dash multi media device, my back up sensors became disabled. After more than 5 visits back and forth trying to figure it out, the crew was able to finally fix the problem and retain all my factory settings with the new in dash JVC touchscreen radio. Thanks again guys for completing the job! I would recommend this great place to anyone in the market for car audio. These guys will get you dialed!
