hey there people, i have f90bt and im wondering how i can get the unit to display mexico maps, i was looking at my current maps and they go blank south of the border..i will be driving down there for the holidays and would like to know if there is a way to get the unit to display a map for down there...any help would on how i can accomplish this will be greatly appreciated thanks
You can get the MX map from the "Updated Maps" thread, check the third to last post. Pioneer doesn't load them because they put the unit over the limit for storage so you'll have to delete Canada or some other place you have no intention on ever visiting.
EDIT: Don't get the update, I am going to do you a favor and package up the three files you need and upload them to my server. Check your PMs for the file loction
You still have to delete something though; Canada is probably best so make your full backup of the unit in testmode, copy the entire cntents of "My Flash Disk" to a blank SD card and put that card in a safe place. Now, go into apl2/iGo/Content
Go into the dem, map, poi and building folders, delete anything to do with Hawaii and Canada (since you'll almost certainly never go to Hawaii too)
Now, go get the file I uploaded (check your PMs) and put the files in the folder they belong in, map, dem and poi.
Now restart the unit, should be working just fine. Anyone else chime in if I left out something.
I have my unit with Texas and Mexico maps. I planned a route from Monterrey,MX to San Antonio,TX just to make sure it worked and everything looks fine.
If you need further info that what terron provided, let me know.
Thanks
once again thank you guys for the help 
i deleted all of canada hawaii and alaska files and replaced them with the one you sent me...and restarted the unit only to find out the mexico still shows blank....anything else you might have forgotten about...i followed ur steps carefully, replaced everyhting still no maps for MX
check your PM, sent you hacked ezRider and new license key
it works now!!! wow thanks for everything god bless you 
Hi, does somebody have the mexico maps files because I cant find them and I already delete Canada and Hawaii. Thanks
Hi, I have also deleted the Canada and Hawaii maps. Can anybody please PM me the Mexico Files?
P.S: These mexico maps only have certain cities and hwys right?
Thank you very much.
Yeah, I only have monterrey, guadalajara and mexico cities. Do you already have the mexico maps? I could send it to you in a PM if you want.
