Beat-Sonic MVA-12L Stereo Replacement Kit for 2002-2004 Lexus SC430 Models with Factory Navigation

This great product integrates the factory amplifier without compromising the sound quality (at least to me).

My SC430 is aging but it still looks beautiful and runs great. I am planning to keep this car for at least for another 10 years, so I though I should upgrade the sound system.
There was no rattle on any of my factory speakers and the Mark Levinson amp., was producing powerful and crisp sounds.
My goal was to replace the factory head unit to a high-end aftermarket double din head unit. I didn't want to buy something cheap now and regret later, and I only wanted to do this once, so I did not hesitate investing money on my audio upgrade.
Choosing a good head unit wasn't that difficult, but finding an installer who knows how to install it was a challenge. No one knew how to do it. They all said that I would permanently lose my factory navigation, climate control, automatic doors for the head unit and navigation and most importantly my Mark Levinson amplifier. After a long research, I found Beat-Sonic who makes a plug and play interface for my SC430. Yes, the price wasn't cheap, but there was no other way of upgrading my radio without this interface so I bought one.

My installer was very surprised with the outcome (since he never heard of this product or the company who makes and sells it), and I'm too very satisfied with the result.
It still sounds like the Mark Levinson, and now I have a new head unit with Bluetooth connection, DVD player, navigation and more.

I was little bit disappointed after I found out that I can no longer use my steering wheel controls except the volume, but there's always a small price to pay for something greater.

I have used an affordable low input (RCA) harness on my SC430, but the sound quality was greatly compromised.
I was hoping to find an alternative sound integration solution to retain the full sound quality and I finally found one.
MVA-12L uses high input speaker wires and it retains the full sound quality.

I had to spend little more than I anticipated but it was worth it.

Thanks Beat Sonic.

I don't know much about cars and audio systems, so I'm going to be very brief here.

I like it. It works as advertised.

Recommendation: Get it installed professionally, if you don't know anything about the car like myself. It's a very expensive kit to toy with.

I studied all reviews and statements about this item on Club Lexus forum before I bought it.
I drive my SC430 every day, so I wanted to spend decent money on my new radio.
I'm not sure if it's the MVA-12L or the new radio, but I think the sound quality has enhanced.

Great product.

Modular OEM connectors, no need to cut wires. Video and steering wheel controls too...a perfect way to upgrade the aging OEM electronics is older SC430s. For a more complete review and a PDF of the installation see my post in the SC430 forum at ClubLexus.com
