The TomTom GO 300 (MSRP US$499) is an economical Mac-compatible portable GPS receiver. If you're looking for a GPS receiver for you car that costs less than a mortgage payment, then the GO 300 is worthy of a look.

The GO 300 has a built-in Bluetooth connection that allows you to connect your mobile phone to access TomTom PLUS services, i.e. Real time traffic, weather and extra downloads such as detailed city maps, additional voices and points of interest (POIs).
