Using a Nexus 7 or any android or idevice and GPS with no wi-fi connectivity

[evident]

I just picked up my first tablet, a nexus 7 16GB for my upcoming vacation. I won't have any type of connectivity when i'm out and about, only when i'm in the hotel room.

I tried using the google maps offline pre-cache thing to download the maps for the area i'm in right now and tried using it to go to work. It was working fine half way then all of a sudden the map throws me in some random spot. When I got to my work's parking lot, I pushed the GPS locator button and it seemed to put me back in the right area. i tried to set a nav back to my home address, but it wasn't able to find it. Does this mean that when i'm on vacation I will need to pin all my points of interest before venturing out with my tablet? Am I correct in saying that it's not as simple as using a stand-alone garmin gps, entering in an address and have it take me there?

My experience w/ navigation and android/idevices are limited. I also have a samsung galaxy s2 but never bothered trying this experiment since I have a data plan which i assume has a helping hand in navigating along with the gps signal. When I had a ipod touch 3g, i could never get a damn gps signal to lock either.

I just used my N7 to get around southern Germany with a set of saved for offline areas that I would make the day before on the hotel Wifi. It worked very well. The only thing missing is the ability to set and route to different destinations. You can however save your route before hand and possibly include a multidestination mode.

It works pretty well, just like you said, the GPS sucks every now and then.

Saving maps for offline use is nice, but the inability to create new routes without an active Internet connection is disappointing and I would also like to know if there is a way to make it work.
