NSW Second`Hand Brethren VW multivan highline 06 -- needs sat nav and tyres

[paul new vdubber]

Hey Guys,
Been reading some posts and pretty impressed with the available knowledge.
Just like Stinky i bought a Brethren second hander with no radio so looking for some good advice on the way to go for the sat nav. Priced the pioneer avicf2obt today and fitted with a rear camera it comes in at (eeeek) $3000. Any better ideas?

Also needs 4 new tyres on alloy rims. What should i get?

Pretty happy with the power doors and seating arrangement and sunroof. Yippee, happy driving!
