Renewing TVIP in Nicaragua?

[brecchi]

I am currently in Leon, Nicaragua and crossed over from Honduras at Los Manos on the 15th of January. I was only able to get a 30 day permit for some reason, but I plan on staying in Nicaragua for about 2 more months. My TVIP expires on the 14th of February. Is my only option to go to the closest aduana (Managua, about 2 hours away) and renew there on the day of? And will I need to repeat this process every month thereafter that I want to stay?
I should also mention that when I asked for a stamp in my passport on the Nicaraguan side, I was told that my stamp from Guatemala (on January 3rd) was what was required (C-4 Im thinking) and would be good for three months from then.
Thanks in advance for any advice, Ben

Thanks for the reply. Im going to take a bus to Managua tomorrow. I have heard of somebody being made to cross the border for 72 hours, but hopefully I won't have any problems and can just pay a few bucks for an extension.

Went to the aduana in Managua today. Was fast, but cost 1 buck a day for 30 days max at a time, so $30. I have to come back after 24 hours to get the actual extension paper, although I did get a receipt.
