"Largest and Most accurate - very large !"4.5 starson by bizloanman
Pros: Best screen - larger than anyone
Cons: not portable
Summary: Well if you want the largest screen and easiest to read while driving - this is the one but as a consequence it is very heavy so forget about taking it on vacation - you will be keeping it in your own cars. Also - it is likely the most feature packed GPS on the market. In cold weather it takes a while for the screen to warm up to full brightness. Also in very warm weather it can overheat so you may need to turnon the defroster to air condition and cool it. But given the drawbacks I wanted the best performing, largest screen and most reliable and this is definately it - I would make the same choice all over again - the other devices are in many cases just toys by comparison.
