I love Sony gear, so this comes as something of a disappointment

Summary: I actually owned an NV-U50T (the predecessor to this unit) before and chose the NV-U51 as I have 2 cars and it uses the same cradle as the U50T so I did not need to buy a 2nd cradle again (the U52 cradle is different).
Summary: I purchased one of these units mainly due to the rugged appearance of it along with the substantial chunky mounting bracket. The first time I set it up I did find that it took about 5 minutes to establish a satellite signal and I was beginning to feel somewhat demoralised about having purchased it.
Summary: While the screen menus are a little slow and the signal takes a little longer to pick up than my Garmin, what is impressive is the array of features. The traffic signal is alot better than the GARMIN 300T I have because of the sheer detail it provides.
Summary: I've had several sat-navs and this is undoubtedly the worst which is a shame as I am normally a HUGE Sony fan. I've re-examined this now though. Firstly, the unit froze several time and I had to turn it on and off, and re-enter destination details again.
Summary: This product is really bad ... it took an hour to find the satellite the other day which meant we got stuck on a slow moving motorway. The trouble is you never know for sure whether the thing will work or not ... an unreliable product is worse than no product at all so give it a miss.
Summary: I recently purchased this item because one it was cheap, two sony always had products I have found to be reliable and three the reviews were good. It is to slow to pick up the signal to load the map.
Summary: Where should I start? Good points - Reasonably easy interface - Cheap Bad points - Way too slow to use within a city really like London. It just doesn't run fast enough - The cradle is too clunky, has too much vibration and just isn't able 2 compete with other manufacturers models - The maps are...
Summary: I bought this sat-nav 4 days before attending the corporate games in Sheffield. What a life saver! We had to attend a dozen different venues all over the city and this device got us to every one without fault.
Summary: It's a good, solid, product, and does what you need it to, but it's not perfect. The screen is good, although some of the icons could be bigger (or perhaps I should buy some glasses), and the voice is clear and loud.
Summary: bought one not long ago, has taken me correctly to five out of six places! but dissapointed that sony havent had any updates to this unit since jan 2006 its now june 2007, i find that sometimes on newer roads you are driving in green fields on the satnav because of the lack of updates.
