Damn it where's 7th gear when you need it?!
Get yourself an RNS-e satnav unit to slot in there instead, they're regarded as giving a better sound quality, plus you'd have the added benefit of a built in satnav system which scummy thieves wont steal in the middle of the night!! Quite a few come up on ebay ranging from £400, they are a direct replacement for the symphony unit needing no modifications to the car. Just take out the symphony & slot in the RNS-e.
