Let me start by saying my laptop is a Dell Inspiron 8200. I wish I would have read the previous reviews before purchasing this product, as I would have seen that it wouldn't have worked.I was very disappointed with many aspects of the product.(1) No mention of any incompatabilities whatsoever.(2) No software or drivers were included (except for Microsoft Streets & Trips, which is a completely separate product)(3) Minimal documentation, and NONE concerning the setup of the PCMCIA option.(4) Pharos website, www.pharosgps.com, has a terrible support area and no relevant downloads or information for my problem.Needless to say, this is going back in the morning, and definitely not recommended for Dell laptop users.
