Officeworks has this Garmin GPS unit on clearance at $165. ORP $499 (On Garmin's website). I've just purchased US maps from Garmin's site using 10% coupon I got after registering the product.
Seems to be cheap for GPS with 4.3" (10.9cm) screen, spoken street names, latest maps for Australia/New Zealand, preloaded speed/red light camera info, school zone speed info.
Device also has advanced lane guidance, bluetooth and access to services for 1 year including weather updates, fuel prices, flight arrival/departure info etc.
Hopefully those that need a GPS find this post useful
Forgot to mention that the cheapest I could find it on Staticice was $441 and $379 (ex shipping) through myshopping.com.au - so definitely much cheaper at Officeworks than anywhere else…
