I have a Spanish cactus 1.6 hdi etg6 feel cool which I took delivery of last September. I love it but it only has the 4 speakers in the front. At my dealer I asked for a speaker upgrade ie two speakers to be fitted in the rear doors. Unfortunately the dealer,having ordered the speakers, discovered that the housings are not prewired and told me it was therefore impossible to retro fit them. Is this true? Secondly, I have a top smartphone with it's own built in satnav etc, but have been told that I can't connect this to the in car screen either via Bluetooth or hotspot. I would apparently have to buy Citroens sat nav or multicity connect to use the in car screen, otherwise I have to prop my phone up on the dashboard. I find this a bit annoying having spent €22,000 on the car. My dealer has told me that for a few hundred euros per annum I can have their system, but I don't feel inclined to pay twice for internet connection. Apart from these two points, the car is exceptional.
