Duncan Aviation's full-service facility in Battle Creek, Michigan has installed an Alto Cadence CMS and speaker system in a Challenger 604. The Alto system was a good fit for the customer, who did not want to replace existing switches with touchscreen cabin controls.

“Although the switches that were in the Challenger were no longer supported, the switches for the Cadence system fit in the Challenger's existing cutouts, which saved the customer time and money because we didn't have to perform a series of interior modifications,” says avionics sales representative Justin Vena. “The Alto Cadence is an affordable, scalable CMS for customers who like the retro look and tactile sensation of actual switches.”

When the Challenger 604 arrived in Battle Creek for exterior paint and an upgrade to ADS-B, the owner requested additional work, including a 12-month inspection, refurbishing the interior and installing the new Alto CMS.

In addition to the new Alto Cadence CMS, the refurbished cabin included two new Rosen bulkhead high-definition (HD) monitors and new Blu-Ray source equipment. Those CMS components all integrate with the existing satellite TV system, and the new Alto switches will control the monitors, source equipment and satellite TV.

“I've heard nothing but good things from the customer about everything we did on the Challenger,” says Vena. “And I believe we were able to accomplish so much because of the cooperation between Alto and Duncan Aviation.”
