We originally purchased a better GPS, but after it was stolen we decided it was best not to buy something that expensive again, so we went with this one, overall it does a decent job, already had it replaced under warranty because it randomly fried itself while we were on a trip. Processing Speed After turning it on it usually takes about 5 min to figure out where we are, a few times now we have had to turn it off and back on in order for it to actually work and pick up satellite signal, but once it starts working its fine, keeps up with everything. Map Quality & Accuracy The quality is decent, accurate enough for what we need it for. Ease of Use Easy to use so far! Easy to understand, find places and addresses you are looking for.
