Recommended upgrades/add-ons for E250 Coupe?

[dkyl]

Just got my first MB, so hope the pros here can give some advices to the brand/location for the following upgrades:

My ride: E250 CGI Coupe 2010

(1) Looking to upgrade the default COMAND system to something with GPS + bluetooth audio for music

(2) Recommended rims, size and tyres for smooth handling

(3) A good camera system without too much wires tangling around <- Turned out that previous owner already installed and hidden secretly at various corners of the car

Command system should already have GPS? Unless yours is the standard audio 20..

Oh then I think mine is the audio 20, the one without GPS and can't even connect spotify.

Not sure if this helps, but i connect to spotify on my phone and stream the music via the supplied MMI cable with a 42-pin-to-lightning adapter. Best bit is thanks to the hookup with singtel, data via spotify is free. =)

Ahh it's a second hand car so no accessories available. I tried using normal AUX cable, but the glove compartment can't be closed with the wire coming out. So it's quite troublesome to open/close the compartment everytime I want to listen to music. I guess the only option is to install COMAND, but felt not worth it considering only 3 more years before COE expires.

Hmm the best solution is to try to get an aftermarket phone mirroring system which cost around 1.5-2k? Compared to spending at least 5k+ on COMAND
