My first was an antenna and software that fit on a laptop. Worked well, but was hard on the laptop batteries.
Upgraded to a Garmin dash unit that worked well for a year or so until it suddenly didn't work. Still under warranty, so I returned it, they refunded my money, I went to the back of the store and got the upgraded unit for $50 less. Can't beat that deal. It's been working fine for a number of years.
I do in-home service work, so I use it daily to find 3 to 5 different locations. It generally gets me within a driveway of where I need to be. One county around here is just nuts with their street naming and numbering and I can't blame Garmin for the stupidity of the county engineers. I've also used it on several long trips and it generally works fine (got me screwed up coming out of Chicago once, but that was compounded by construction detours). The only annoying things I don't like about the navigation is that
- Once it calculates a route, and you decide to go a different way, it will do it's damnest to get you back onto that route, even in cases where the street you are on parallels the original route then eventually merges with it
- It weights certain events too high in its "cost" algorithm. It constantly wants me to drive a mile to the next exit, go through additional stop lights, 2 4-way stops, a residential district, just to avoid a U-turn that I make every time on the way home.
- It doesn't learn. You would think that if I take a certain route all the time, or make a U-turn at a certain spot, it would accept this, OK. No, it's like a fresh start up every day.
We took it on an Alaskan cruise a few years ago. When the ship docked, I marked the location (so we could find our way back), then I could use it to track where we wanted to go, find places to eat, and figure out just where in the heck we were.
I got another dash unit Garmin for my wife when I saw it on clearance at Office Depot for $45. Navigation is fine, but the touch screen is really picky -- much more difficult to use than mine. Also I can't understand why it has a completely different user interface. Changes for no apparent reason.
