it take a lot of research for I to finally find a gp cf bundle -lrb- hardware and software -rrb- for a Dell Axim x5 . some how just buy the one Dell push be not good enough and here some of what I have learn ... the Pharos unit cover the audio input on the top of the x5 ... why be that important ? well if you be use it in a car and what to use a device to boost the sound of you turn by turn direction -lrb- ie . a power PDA car holder -rrb- ... well you would be out of luck . the product have a lot of kink , it have trouble with re-routing and over all be a good start but for the same money you can get something that be much better . look into a Haicom 303 ... as far as software a lot of it be personal preference - look at the website of the software maker and see if you like the look of the software . call Pharos and talk to they ... I think you will find that they be more about good marketing , slick name and packaging than a mature product . like other reviewer I can not see any difference beteen the pf022 and the pfd22 -lrb- for Dell -rrb- other than something for Dell . check ` buy GPS now com ' for more in depth information about GPS and software product . Amazon have a good start but there be just not enough imformation - like EXACTLY what come in the box and any thing else -lrb- ie cord -rrb- that you will need to make it work with you pda . since you can not return software once you have install it - you need all the INFORMATION you can get to pick wisely .
