No need to sh!t a brick toilet. Mexican plates are almost identical to US approach carts. The only real differences is that they like to use tear drop procedure turns, transition level and transition altitude are usually different (found in the notes section part of the briefing strip, usually 18,500/FL195) and there are different speed limits in Mexican airpspace. The charts themselves are not exotic or hard to read. Just know some of the ICAO symbology which is in the chart legend of any set of Jepps.
