Retrofits at the 9-3 Anni

We drive a (suck**en) 9-3 SE Anniversary BJ/EZ 2002. It has to be remodeled now 🙂 and will learn Step1 from Hirsch. Further, I would like to make the following upgrades, for which I am looking for daily suitable(!) solutions. I have read a lot, but I have not become really smart: a) Upgrade with a hands-free device for a Nokia 6310i (which I can see if Tel 1/2) is pre-equipped?) b) The sound system needs to be improved and an additional CD-wake d) Has anyone ever had positive experiences with a sliding roof retrofit (e.g.Webasto)? e) Is there also a good low laying around 15mm/20mm without the tires grinding and the car in the TG? f) Search mesh grill black (incorporation difficult?) g) Change of the gear lever (hand switch) a problem? I know many questions, but I am confident. Please remember, since ss I have no own workshop facilities. stelo …who soon has the Saab for himself!
