I have had two TomToms the first one lasted 6 years the second about 8 years, it was working ok when I discarded it , just out of date. I bought a new Garman from Amazon about 18 months ago it went wrong after about three months , and was replaced by Amazon. The replacement lasted just over 12 months , and the same thing happened as with the first, it kept freezing up. Amazon game me a full refund, even though it was over 12 months and out of guarantee, which I was pleased about. I went to Halfords which is a well known car parts, cycle, every thing you need for them shop here . I bought a new Garmen, I had it less than 24 hours and it went wrong ie it froze up , and the writing was all in Japanese , I took it back and was given a replacement, so far so good.  I don't know if this means that the Tom Tom is better, or if it's because they are all more technical now, so there is more to go wrong with them.  

I know two people who had Tom Toms and both switched to Garmin. One says he likes the Garmin a lot better. The other says he will go back to Tom Tom because it is better. You're welcome for my help!       :)

All  the stuff I saw suggests Garmin.

We use to use our laptop with the Delorme GPS unit. Now we both have smartphones. And the technology is so much more that it was 15 to 20 years ago. I don't think I would bother with a Garmin or Tom Tom. Mine is a Moto x hers is Samsung s6.
