About to purchase a 2004 GX470 from a family friend this week. $8000, 70K miles, non nav, looks to be in great condition. Family Friend has business abroad every other month, so he only drives it when he's in town. Car is garaged otherwise. (He is going to get a 2021 GX to replace it.) The car is being taken to the local Lexus dealership for a check tomorrow, and my Dad is going to have everything that needs to be serviced completed. (He lives in Oklahoma, and will be shipping the car to me). Since this is a 2004, I would like to upgrade the tech first. I have read up on the phoenix tablet, but that seems too buggy for me at this point, and will likely just go with an nav screen head unit. I also would be interested in backup cam, or 360 view if theres a decent aftermarket system out there. Any recommendations or links that could help point me in the right direction for upgrading the tech would be greatly appreciated. Excited to be a part of the club!
