Mine's a 6, Gen 3. Fortunate that the 2.4" tires came on it. Love the quality of Trek bikes! Bought it last year after my Dawes 1500 (UK bike) got stolen. Carry a chain now to try and deter another theft.
I changed the battery in my old Garmin NUVI 52 (no dash cam) and it was a delicate process because they design them to be difficult to change so you will be encouraged to but a new device (planned obsolescence). I used it until it died again and then upgraded to their Drive 52 which I still use.
Here is my experience with the GoRhino:

Right. I was pleasantly surprised when the service tech who did my last oil change adjusted the pressure to my oversize tires correctly instead of using the stock psi on the sticker! :like:
Hey Bob,
It is really worth it...here are the services they performed...
Cleaned bike. Installed new chain, brake pads rear. Adjusted derailleur, brakes, checked headset, bottom bracket and hubs. Trued wheels. Torqued bolts. Lubed chain with Finish line dry lube. Lubed cables pivots, greased...
Transported the bike to the shop last weekend for a Level 2 service with 161 hrs. on it. New rear brake pads and new chain installed. Came out squeaky clean and runs like new!
