No MapMedia hasn't established any update date for the next revision. I am not sure why CMOR is finding it necessary to update that region so often. I expect they are minor changes and most customers are not willing to pay the full price again for a minor update. I suppose it is a good way to push sales. There is no upgrade discounts for CMOR due to small customer base and the costs of converting them to the proper format. I am sorry, we have no expected date to offer. Having the TZT3, you might consider the DFF3D if you don't have one. The PBG with that has been very good. I will pass your desire to buy the update to MapMedia.
