Need help finding an aftermarket stereo for a 2003 Honda Accord EX?

I bought an Accord 3 weeks ago and the factory navigation system doesn't work. Thankfully the A/C works but my issue is the fan controls are in the navigation system. So I can either put it on full blast or off. What I'm having trouble finding is an aftermarket stereo that will fit, be compatible with iOS devices, and most importantly, has A/C controls. The dealership by me said they can fix my system for 2k. I already paid 2k for the car so you can understand why I'd like to not have to pay the dealer more money I don't have haha.

Should I change my transmission fluid?

I have a 2009 Honda Fit manual transmission. I bought the car with 100k now 145k and never have had it changed. I've heard horror stories to not to change it on high mileage cars which is why I haven't had it done.

Are Honda Fit's good/reliable/safe cars?

I feel like these are good first cars from reviews etc… And I could get a used one at a decent price (below $6k). Anyway, would you recommend a Honda Fit for a first car?
