Recently @ CES 2010 PAC released a product that gives the avic z110bt (and others) the ability to use remotes. No lag and if used with the correct remote then it also allows activation of the voice function right from the remote!Not sure why pioneer removed the IR but this little add on from PAC is just what I was looking for. Part #: WRI-P works best with (CD-R510). This product completes the unit by giving it what it should have had in the beginning!
PS. I love this forum, thanks to all Mods and members on this site!
