wired remote may be the best way to go, unless you can get a IR extender to use a wireless remote...

IR is like a gunfight; "accuracy/line-of-sight=line-of-fire".

There are IR extenders (IR receiver module on a cord) for home units, --i wonder if they have them for car units...so you could to route to the underside of the dash lets say, clipped to a cigarette lighter mount and poof. IR.
