It is quiet .One problem I have is how to secure the unit so it can stay up in the car, a problem during car movement, stop and go. The connector can be easily disconnected and the unit does not turn on automatically when the engine was started. It is difficult to see where the start button is since the screen is all dark without power.Thanks again Jane for your excellent customer service. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.lk/products/146545350-day-dawning-adh50b](https://www.desertcart.lk/products/146545350-day-dawning-adh50b) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-05-24*
