Add factory options, value, to your Tacoma
To clarify, this came as a factory option on 09+ Access Cabs.
May be able to retrofit to other years.
Although I already have my own system and not interested in this per se,
I would have to agree with you that this would be a simple install on lots
of vehicles. With the built in amp, you can just splice any speaker wire, run
your power, ground and remote and then mount the thing anywhere.
