I have a Nuvi 5000 that just replaced my nuvi 680 (transferred to the wife's van). The 680 was great, and still is. The nuvi 5000 has a slightly larger screen (5.2") but a few less features than the 680. My father-in-law has a nuvi 250W and really likes it as well. For the titan imho, I wouldn't get anything less than the 4.3" as you are a bit away from the screen as you drive. I have mine mounted in the large recessed storage on top of the dash/radio cluster. If you search there is someone who showed instructions on how to mount and wire it up so you don't see the cigarette adapter plug and no unsightly wires. I've had a Sony NAVU (3.5") some time ago when they first came out and am very happy that I moved to the Garmin. There are lots of options and price points with Garmin so you can pretty much pick the features you think you need. Hope this helps.
