The recent recession has taught us many lessons. Especially, I have learnt to spend carefully and make sure I get back 100% of what I spent (on products we purchase).
There will be some products in the market, especially tech gadgets that differ very less in terms of pricing but very much in terms of features. In that case it is very essential for you to make purchasing decisions carefully. Moreover, some tech gadgets are once-a-life time purchases or at least once-a-long-tenure purchases.
The recent technology in GPS car systems has enabled car owners with many features. To add an extra feature to your automotive GPS system, the price required to spend might be very less. But make sure that the feature will help you.
A few features that you might want to choose from are PDA/GPS hybrid tracking system, automatic routing, voice-guided navigation, route re-calculation, real-time map upgrades, etc.
