Compare reviews on navigation systems by reading articles on sites such as ConsumerReports.org or PCMag.com, because these often take user reviews into account. It is also possible to use the comparison tools from online retailers such as Amzon.com or BestBuy.com to see a summary of specifications and reviews for different products on the same page.
One method for comparing navigation system reviews is to check an online comparison guide, which typically covers the best and worst features of several different models according to the experience of the reviewer along with common customer complaints. These reviews often cover features such as the accuracy of the models, additional features and ease of use. When comparing critic reviews, it is helpful to pick a single data point to understand the differences between reviews and gain greater perspective on the product.
BestBuy.com offers a product comparison tool that allows you to look at the difference between up to four different products. Many listings on Amazon.com feature a similar breakdown of related products within the same category, including a list of the different customer review ratings for each item. When reading customer reviews, pay attention to the review date to ensure they refer to the latest product and not older models. Also look for patterns in complaints within a particular model so that you can check other models for the same issue.
