I did a couple of searches and could not find the answer to this.

I am the second owner of this truck, and I appear to have the premium Infinity sound system with the 10 disc CD changer in my '98 full size Montero. My factory radio lost power and is now asking for a 4 digit security code. There doesn't seem to be anyway to bypass this. Is there anything I can do to get this working? I don't have the extra cash to purchase and install an aftermarket system right now. Thanks for your input.

'82 Toyota Supra, Spearco Turbo Kit and too many mods to list (in need of turbo rebuild)
