The owners manual for my 2007 Honda Odyssey seems to indicate that the timing belt should be changed at 60,000 miles for extreme driving conditions. It's not clear what the schedule is for normal conditions. I've heard 90,000, is that accurate?
The manual should have a section for "normal" as well as "severe". Given the expense of repairs on an interference engine (which I believe all Hondas are), I'd be inclined to replace it on the "severe" schedule unless I drove 20,000+ miles a year all highway. Severe service may include cars that are not driven lots of miles in a year as some items (typically belts, hoses, tires) are time limited in addition to wear limitations.
I see that the online Owner's Manual for your vehicle does not specify the mileage and rather defers to the Maintenance Minder feature of your vehicle. This is unfortunate, I can check the service manual later and see if it species whether the maintenance minder is hard coded or if it would produce variable recommendations like some other vehicles are starting to do based on programming around your driving characteristics.
To my knowledge, under normal driving conditons your maintenance minder should have you change the timing belt, get a major tune-up and have valves adjusted at 105K. It's a really big hit on maintenance... but after that you are fairly low maintenance until 210K!! (supposedly)
For our 1999 and 2005 Odyssey LX models this was the dealership recommendation for our driving type.
