Just an FYI. I dunno why, but the Mexico NT Maps dont have much coverage at all in Cancun. It does have very good coverage in Playa Del Carmen. The Bicimapas have very coverage for both. However, some of the info like roads may have errors. I have contacted Bicimaps before on this issue. BTW, if heading to Cancun this spring break, make sure you have your passport as it's soon a requirement to gain entry into Mexico.
