I would recommend looking over all the MM3 available charts of your area using our Chart download filter at our website. It depends on what your looking for. For wide Navigation needs along with good bathy line charts (fishing charts), I would recommend C-map. For select bathy photo of relief bathy CMOR is very nice but a bit limited coverage area and costs a bit more. Some people buy both. If you have an existing license to MM3 c-map you can get a upgrade price from you dealer (normally half price) normal cost. CMOR charts are purchased directly from CMOR and not aware of any discounts on upgrade.

Thanks! As usual, helpful forum.For the TZT3 MM3 chart - CMAP you have already have license to, an upgrade is half price of normal price. Just make sure to tell the dealer this an upgrade of an existing license so you can get the discounted pricing.
