I recon your looking at £600 plus ........ Ok the P12 sat nav is good, but not worth that kind of money
Yeah the Tom Toms are good, it depends where you fit them, if you just sucker it to the screen it looks pants but a properly thought out install ...... Wit hthe perminant install kit would do ya fine
I recently nipped in my car radio showroom & the dude salesman really thought he was going to get me to buy a Pioneer radio/cd/satnav combined unit for £2k...... I was tempted till he told me the updated cd's are £300 each & they are usually 3 years out of date .............. At that point I realised I nearly got schlepped by a salesman ........ Tom tom go for me
