You may or may not be aware of the many options on today's market when it comes to auto navigation systems. Take my word for it there are now more options than ever before with new options appearing daily. Among the many options that are available for those of you who are interested in obtaining equipment that will assist you in finding your way on long and short trips there are options that can be used along with your laptop or PDA devices. If you currently own and use on a regular basis a laptop or PDA the software or other devices and receivers that are required in order to utilize your laptop as a GPS device aren't nearly as expensive as purchasing a stand alone auto navigation system.
