I have a J572KC. I want to give it a satnav but don't know whether to go with a TomTom/Garmin type or replace the existing radio/cd player with a 'built-in' model like Columbus or similar. Any suggestions most welcome.

I'v just put a Kenwood VW / Skoda / Seat unit in my Roomster , plenty of things to do with it, just think that it is not going to be in your eye line as a stand alone one on the dash would be, what you want to pay for one will decide I expect. Good luck

I prefer satnav in the line of sight as it is less distracting and does not require to take eyes off the road as much, so brodit/proclip mounted over the air vent works best for me. Have been using TomTom/PDA for many years, an added bonus is that you can move satnavs between cars, comes in handy when we go abroad and take a 2nd one as a spare

Thanks for the responses. One each way Price isn't all that important. Just looking for other peoples opinions and experiences. Have read some disparaging reports about the built-in models. Wife's car (a Renault) has a built-in satnav at eye level. She likes it that way.

The Roomster has a mic slot in the overhead light fitting. Is that pre-wired for phone? Also noticed there is a 'fitting' on top of the dash above the instuments in front of the driver. I'm wondering if that is for a GPS receiver/antenna?

Not pre-wired, but I have just installed a Parrot kit and (crudely) cut out the mic 'vent' to allow for better sound quality for the calls. I'll source another one and make a tidier job someday.

See my build thread for install.
