Re: Adapter for armrest USB with aftermarket headunit?
Not sure specifically on the armrest USB wiring websurfer, but generally, if your aftermarket head unit provides for a USB input then the armrest wiring should be able to be retrofitted.
As you may know, many aftermarket receivers provide for USB ports that will even allow the head unit to control an IPOD allowing you to leave the device stowed away in the armrest. IME, they are worth the premium to get this control ability up on the dash.
Which unit are you looking at?
