Is it possible to put an outside volume remote on the radio? I have no steering wheel control. I know pioneer has steering wheel remotes for other models. Is it possible to make it work for my model? The volume knob on the 910 is useless..... Other than that, it is a great unit.

yes, you can get the steering wheel controls adapter and make your own buttons on the dash for vol up and down, you can get a new steering wheel with the buttons (if that option is available for your car), or sony makes a wired remote that will work with the pioneers as a few have used it before.

Get the PAC WRI-P and a Pioneer wireless remote. There are threads here that give details.

Do you know what the model # for the sony remote that works with pioneers is?

RM-X4S. But be aware the polarity on that remote is reversed so all of the controls will work backwards on the Pioneer's. There also no longer made so they will be hard to find. Your better off looking into the suggestion I made above.
