Carcomm International recently released a car cradle which is designed for the HTC Himalaya platform (known as xda II, PPCW.Net i-Mate Phone Edition and others) with original bottom connector and steady fitting for your Phone Edition.
Specially designed for mobile use it's charging through the 12 Volt cigarette lighter and also includes a RS-232 and a PS/2 connector for connecting the device with other external accessories, for example a GPS Receiver.
It's available from several online shops like suplies4mobility for around 70 - 75 Euro.
