Today the GPS I bought from Amazon.com arrived. It is Garmin Nuvi 1450.
After lunch, we went out and tested it outdoor. It took a few minutes to acquire satellates. It is normal for the first time use. After that, it won’t wait so long.
I read the manual carefully in the afternoon. Registered the product on Garmin website. Mounted my nuvi to my car windshield through a suction cup mount and a cradle. Tried it on the way to pick up Eric and on the way home. It’s funny to hear it says “recalculating” when I don’t follow its suggested route.
