I definitely agree with that - I'd take out the fuzzy hole and custom mount a cig lighter jack to some metal piece in the dash to keep it stable...

My suggestion: upgrade HF kit and get the profit, that solution is MUCH better. More flecible for your needs.
I'd do this, except I upgrade phones every 12-24 months and these all-in-one HF kits are very convenient for this!
