I can only assume all the other reviews are for the new 910. I have a refurb, Hard disk version, which cost £90...Best money I have ever spent. Bought it to go on a long holiday in USA, crossed many borders..UNIT WORKED 100%, VERY ACCURATE, NEVER FROZE, VERY EASY TO USE.. As for being sensitive to temperature, I used this in death valley at 160 degrees ground temperature..car A/C failed, Tom Tom never skipped a beat !!!!!
The cost of this unit in the UK was less than the cost of hiring one in the US so the unit is now free !!!
I use it all the time here in the UK & it is really reliable.I have not tried the map upgrade facility as....WHO CARES !!!!!!! civilian satnav is only an aid, If you want 100%, get a military spec differential unit. VERY PLEASED, WOULD BUY AGAIN..
