HD7 GPS functionality w/out data plan?

[a3p3g]

I have a HD7 that i recently had to ditch my data plan unfortunately (i start to twitch during the day sometimes now

can anyone tell me how functional (if at all) the aGPS chip will be to me w/out a data plan on this phone? obviously i'd need to be using an app that supports offline maps (I know Navigon is releasing their app for the US this fall that will have full US Maps).

i guess i'm curious if its even worth trying or if that assisted part of the chip is that crucial to accurate positioning/navigating. hoping i'm not screwed out of another great feature !
thanks for the help

I would think it would work, but it will just take longer to get a fix on your position.

i wonder if once it locks my position if it would have a problem holding it / tracking me
