I've had my 06 TSX 5AT w/ Navi since new and now have almost 150,000 miles on her. Extremely reliable vehicle and it will take you +200,000 miles with routine maint and a few wear/tear items like alternator, power steering pump/rack, or suspension parts. That color of TSX is very hard to find; especially, if the paint in good condition, low mileage, and up-to-date on services. I've handed down my TSX down to my kid in high school back in 2014 and he loves this car and it is still going strong in his sophomore year in college.
My kid doesn't even turn on the navi screen because of being in the smartphone generation. It is just a college run around town car anyways and Navi really isn't needed. He mostly plugs his iPhone in the AUX connection for downloaded pod casts, internet music, or whatever music already on his iPhone. He is also that generation that doesn't like to talk on the phone; but, will text all day. He doesn't get a lot of use from bluetooth handsfree. There is a spot in the center console large enough where you could add an in-dash 1-din stereo system pop-up navi screen. Then you could add bluetooth audio streaming, back-up camera, apple/android carplay, waze, weather/traffic, etc...
The navi looks nice; but, I don't think Acura will support this model year version for much longer with update disks? Acura stopped making update disks for the previous gen navi for the 2004/2005 TSX in 2014 (orange disks). The 06 TSX has an updated navi system and I give Acura 2-3 more years before they stop making white DVD update disks.
Another thing to keep in mind is there are probably 2X-3X more TLs in the same model year as the TSX for just a little bit more in price. The +2006 TL will not handle the same as the TSX and might have a lower reliability compared to the Japan built TSX. The plus side to picking TL or TSX are:
- more hp/tq (the TSX 2.4L and power sucking 5AT can suck at times)
- still get the smooth 6MT in both vehicles if you wanted to go manual
- mpgs are almost the same
- touch more room in TL
- more luxury look inside and out for the TL
- prices can almost be the same for both; mileage and condition determines final price
- just as many mods or you can leave stock for both vehicles
- will need to mod the TL for it to handle like the stock TSX
- almost everyone would take a 3.5L 07/08 TL Type-S in 5AT or 6MT if you can find one at a reasonable price
Another option in the TSX and TL price range is the 1st Gen RDX. It is pretty much a TSX with more room, same tight handling, all weather capabilities, more hp/tq from 2.3L turbo, same excellent reliability, easier to park/maneuver because it is shorter than the TSX/TL, much better 360 degree visibility, more updated tech, and tons of utility if you bike/hike or need to take friends.
