I wrote the following back in September. I had a Tom Tom for about 2 weeks and sent it back and bought a Zumo 390.========================
I'm sending my TT back tomorrow also. Can't beat the no cost 30 day trial.
Hell the TT has a compass that has east and west wrong. The processor is much slower than any Garmin I have ever used and I've had many models since 1990 when I started using them on my boat. The worst thing was that it can't even follow the simple route I programmed for Saturdays ride. In the middle of the ride I could not get it to finish the route for the last 50 miles. It kept sending me back to the stating point no matter what I told it. Coming from a Garmin I found the menu structure to complicated. Way too many steps just to load a route. I think it was 10 button pushes to load the route and another 5 just to cancel it. While following the route I created(before it caused a problem) I hit the gas station quick link button and TT locked up and shut the unit off. I restarted and tried again only to get the same results. At the gas station i tried it again and it worked fine, but who cares I'm already here. At lunch we were only 3 miles from our destination but no matter what I did the TT took me back to the start of the route and back to where I was, 190 miles. Good thing I'm not stupid enough to follow it. On the way home I just hit the home button and the route worked OK. It's idea of the fastest way home and mine were slightly different but nothing worth griping about. I did like the fact that roads were named with both route number and name. I never liked Garmins using name only for major routes.
Not sure what I'm going with next. I'm going to check with Garmin to see if they still refurbish the 550. If so I might go that route along with a new cradle as that should get me through a couple of more years. It would be well worth a couple hundred bucks to me. If not I'll be looking at the 660 and new 390 very soon.

This may be the case but this has not been my experience at all ...
If it was as bad as you are saying, then you either had a bad unit or didn't update the software ... No question about this because mine does none of the things that yours did ...
In any event, as I said earlier, it is less refined than the garmin and so on ... It does not speak street names for example ... It just says "left turn in 500 feet" etc etc ...
For half the price it does most of the things I want and it is missing a few things ... For instance, it does have bluetooth to my helmet speakers but not live traffic ... I wish it had live traffic ... But, it does have lifetime maps and so on ...
So, there are some trade offs. It is probably not as "nice" as the $800 Garmins (The screen is a tad smaller)... But, as I was looking at it, it has not failed to get me to a destination yet, the routes work if you do them right ... the map looks ok but not super hi res ... It is waterproof and comes with a nice mount ...
For half the price, it got me the items I cant live without and allowed me to be the kind of rider that uses it maybe 10 times per year on trips etc ...
If I was retired and riding all the time on long rides to new and exotic places maybe I would spring for the garmin ... (Probably not but maybe) ...
As I said, It gets me to where I am going, is waterproof, has bluetooth and lifetime maps ...
And as a bonus, it is only normally overpriced as opposed to ridiculously overpriced(Garmin) compared to a car unit ...
