I recently had my car diagnosed and it's confirmed that I need a new head unit, but they quoted me 1900 for a refurbished one, and north of 6000+ for a brand new one, has anyone had any luck on aftermarket ones that aren't as expensive? or am I better off just coughing up the price for a refurbished radio? thanks!

 

To date I've not seen an aftermarket radio available/installed in a 3IS.
The radio is such an integrated part of the infotainment system that it will pretty much cripple the rest of the system when it's removed.

Hopefully someone may have another suggestion.

 

Search here or call them, they part out cars.. I've bought many parts from them in the past.
