HP has partnered with ProClip on a site that offers car mount kits for your iPAQ or Jornada device. The site, www.ipaqcarkits.com, offers a shopping wizard to help you find the right mount and device holder. Essentially, it’s a modular solution where you get a mount that goes into your car and can then get different holders for your different devices.
The site also offers mounts for other devices such as the Apple iPods, Dell Axims and many other Windows Mobile devices.
