Sat nav and dab head unit recommendations

[Silenoz]

Just looking for some advice as this is a little bit out of my comfort zone.

I bought a 2005 Toyota Corolla last week to take the commuting strain. It's a nice car, but only has a radio and cd head unit. I've been a bit spoilt with my last couple of cars so would like to add a unit that will give me navigation, dab radio, Bluetooth connectivity for my mobile phone. Does anybody have any recommendations or pointers of who I could talk to about getting something installed? I don't really fancy having to go to Halfords!

Thanks.

Thanks for the reply. I live in Widnes. There doesn't seem to be any audio places around apart from Halfords.
