Pros: Quick, route calc and re-calc is faster than the old Garman. Bonus, she does not say "recalculating" every time I pull off the route, she just goes straight to the next way to get back on track.
Map Updates are good, and the ability to report blocked roads from the location is nice, but in Toledo, OH, I came on one Dad said was blocked for 2 years. Does nobody out there report these?
Lane assist and realistic photo of turns is great, would like it to go to photo mode sooner, but it does help.
Traffic has already saved me hours of waiting.
Voice Control helps keep eyes and hands on driving. My wife didn't like running the old Nuvi while I was driving, and now she or I can do it without taking it off the mount.

Cons: Wasn't obvious the ability to receive Traffic is built into the Car charging cable it came with, Or I just missed that nugget in the book and quick connect guides. First try with the same cable from my old Garmin, popup clearly notified me there was no traffic capability. Searched box, then noticed the cable on the new PSU slightly thicker, plugged it in and got traffic.
Also, at one point with traffic avoidance turned on, the main road was shown as heavy traffic on the map, but she still told us to turn onto it. We went around and the Garmin adjusted nicely.

Other Thoughts: App Extensions are good, but the name "Extensions" could apply to several devices connected to my phone. I still sometimes must pause to think "Which one device does not put it's own name there?" Should change it to "Garmin Extensions"
Battery stays charged better when left in from the heat days at a time. Then again, the old one could have just been a tired battery - I had replaced it over 3 years ago.

Pros: Lasted for 3 weeks

Cons: Worked for 3 weeks, then would not turn on when plugged into car power. Would power on and off when plugged into computer. Talked to Garmin customer support. They said bad port, this model is old and has a known port issue. They hooked me up with a replacement substitute model because they did not even have any 2595s to replace it with under the 1 year Garmin warranty.

Pros: What I liked in the Nuvi 2595LMT
5" screen
Voice Commands
Speaks street names, turn by turn
One button to save and name a location.
Free map and traffic for life
Highway Lane selection
Highway Exit enhancement
Highway speed for that highway
Speed limit exceeded notice
Pedestrian mode
Can change icons and voices
Has maps for most of Mexico
Select multiple routes and not just one
You can add coordinates in for a route which I use a lot.

Cons: None

Other Thoughts: I used the 2595LMT for a trip across the USA. Previously to this unit I used an older Garmin nuvi 360. There is really no comparison between the units, this one is so much better than the old one.

Screen:
I larger screen size is really nice at 5". I was impressed to see the exit signs pop-up on the screen showing me which lanes I should be in. The top left corner also shows a bright white lane indicator as to where you should be with dim indicators as to where you should not be. Also nice was the fact that at the top of the screen Garmin tells you what you will be doing next.

Screen Features (called layers):
I went into the layer options to turn on some added detail for my trip. I activated the screen layer to show me: time for arrival, miles remaining, altitude (really cool to see why the truck was slowing down as I went up a mountain), my speed, and the road's speed limit.

Speed Features:
- Don't turn on the speed limit audible notification, it will drive you crazy with the 3-beeps every time you go 1 mile an hour over the posted speed. It drove me crazy till I pulled over and shut down the noise notification for going over the speed limit.
- It will still show your speed and the speed limit without the audible alert on.
- I liked this feature and found that the Garmin was more accurate than my speedometer when I passed by an outdoor "this is your speed" sign.
- Sometimes when Garmin shows a speed limit it is not accurate. I wouldn't use their limit posting as fact. It may have been more accurate had I updated the maps before I began.
(Update 7/25/2012)- I spoke to Greg at Garmin about changing the tolerance from 1 MPH to 5 or 10 MPH over the speed limit. Per Garmin this currently is not an option as it is programmed in their firmware. He thought this would be a good idea too and suggested I request this in a firmware update. I did. If you own one, please request this feature too so Garmin sees that a speed tolerance of 5 or 10 MPH over the limit is a feature we would like to have in an upcoming software update.

Directions:
- Garmin speaks the names of the streets and this newer version no longer says "Recalculating" if you miss your turn. Instead it just changes your route to fix your mistake.
- The upcoming directions is displayed at the top of the screen so you know what you will be doing next before Garmin speaks it.

Bluetooth Phone Tie-in:
- I linked the Garmin to my phone so I could make and receive calls through it. When someone called my cell phone an icon popped up on the screen with a ringing tone asking me to "Answer" or "Ignore" the call. It was so much easier to answer my phone this way, by touching one button on my Garmin, than digging for my phone and sliding it to unlock.
- The negative however is the fact that the person's voice coming out of the Garmin speaker was not as loud as it could have been. This may be because the speaker is on the back of Garmin. If the caller talked loud and clear things we
