I'm planning to upgrade my sound system by changing my head unit to Alpine IVA-W505 multimedia station. As I read the options or available accessories, I got interested with Alpine PXA-H100 IMPRINT audio processor. Then I became interested as well with Alpine PXA-H701 multimedia manager. I would like to know if it is ok to install both of these units to the IVA-W505 without making some sort of redundacy when it comes to function or if they will complement each other. Thanks.
