Can't even find a GPS signal

We purchased this product for your basic usage and we didn't want to spend a bunch. This product can't even find itself! It can't locate a signal from our cul-de-sac. Half of the roads in town aren't on it and did I mention that I can drive all around without it finding a signal!!! Unfortunately, we've relied on it too many times and been stranded. Now it is money down the drain.
