Recommend any car audio install shops in NOVA?

[Tex]

I'm looking to get an estimate on installing a nav system in my CX-7. Any recommendations for car audio shops in the northern VA area? I prefer to avoid places like Best Buy.

It's not really that difficult to do it yourself, (eao just did one). Most shops aren't that great, just a step above bestbuy unless you know of one with high levels of recommendation/experience. When doing navi they think they can charge astronomical install fees too, just because it's nav.

Tweeter, in Tysons/Vienna. Ask for Tommy Chan He is a sick installer...
Highly sought after and his work is money. Tweeter prices are displayed so you know how much your gona pay upfront. I've been doing my own AV stuff for years and Tommy was the only person I trusted to do my work.
