No. If you want usefully updated maps, then you have to pay for them. Garmin do offer a "lifetime" maps subscription, but it's only for the lifetime of your product: given that most Garmin SatNav units don't last long enough to benefit from more than a couple of years worth of updates it's usually cheaper to buy the single update option, although the lifetime subscription gives you four updates per year and one-off is just a single annual update.
If your unit also needs updated traffic and camera alerts then it can be cheaper to buy a new satnav.
