I need to find a free jensen gps map update, where do I find one

SOURCE: Free map updates

Unfortunately, they don't offer free map updates. You can purchase map updates for around $70, but they won't update them for free.

Also, the base model of the C330 does not have enough memory to store the entire 2008 Map Update. Unless you have more memory than it came with stock, you may have to choose which maps to include. For instance, in North America you have to choose between US and Canada - there's insufficient memory to hold both.

There are no free map updates for the StreetPilot Series.

The newer models do come with a free update that must be downloaded within 60 days of purchasing the system.

There are utilities for adding POI (Points of Interest) as well as Browser plugins that can be used to add Favourite Locations from Google maps. these updates are available from the garmin website.

On Garmin gps there is several ways to update your maps you can buy the sd update card, the cd, or upload it from the garmin website using a usb cord sold seperatly. the updates can range from $70 dollars to $120. I work at best buy and we carry all the updates for garmin

Asmany as there are FREE dinners Updates are not free, unless you paid full price for it when you bought it. Free upgrades are a deceptive myth. If you get a free uograde its usually minor and was included in the price of the pack.
