Took my time with the install, but once it was connected, the databus integration kept everything working instantly—even the chimes I was worried about losing. Saved a ton of headache compared to hardwiring each feature separately.

Wiring this in was surprisingly straightforward, and the fact that it taps straight into the databus means my factory chimes and steering wheel controls all came back without any extra modules. Took me about an hour from start to finish, and everything just worked on the first try.

It took a little longer than expected to figure out the wiring, but once it was connected it retained my factory chimes and steering wheel controls perfectly.
