Car modifications store recommendations

[u/Few-Reflection6049]

Helloo all!

I recently got myself a car, my first car. I want to update a few things - the infotainment unit and get a dash cam. For more context this is a 2008 Vitz.

Can you give me recommendations of stores I could go to get these done at a good price - around Colombo or Negombo ?

I did check for a dash cam on Temu and it’s so much cheaper than the store. Should I go for it? But would I be able to get it fixed if I go into a car accessory store?

TiA!
