The strange edges makes it quite difficult to attached to the dashboard. It is not as sleek as the Lyra. Too Heavy and way too expensive even the 20GB model. Its all-plastic compared to the Lyra that at least uses aluminum ofr the back for HDD protection. The screen is better though, that's all.I returned my item because I thought I could get used to the weight and shape of the thing. Because of its odd shape, it doesnt really look very well installed in my dash.I will have to wait when they revised the shape to be more like the Lyra.
