Hey Guys, I have an AVIC-90DVD (remote control) unit hooked up to a custom display. I am currently using the CNDV-40R disc but am tired of new streets not showing up. Is there a successor to this disc that will work on this unit? I noticed the CNDV-70MTP works with the AVIC-90DVD only if it is used with a Pioneer Touch Display. Is there any way to bypass this? Any help is appreciated!
