I bought one for my 2004 LC100 from Phoenix automotive and installed it. No sound so their tech support sent me a video showing how to strip and splice two wires together and got sound. Really great sound. Way better than factory. But there is moderate static sound at all times. Was was on the line with tech-support for three hours yesterday and still no fix. We were also trying to get the back up camera to work and still no luck. For $750, im still happy i bought it. I will be thrilled if we iron out those last 2 issues. It is fast and has tons of cool features. Fits and looks awesome. Just be ready to spend a few weeks fiddling w it to make it work. Tech support is good but you have to make an appointment a day or two in advance.
